The remote AlmaLinux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2023:5093 advisory.

  - Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()`     failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace     (CVE-2023-31248)

  - A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. (CVE-2023-3610)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
    (CVE-2023-3776)

  - A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the     nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local     user to crash the system or potentially escalate their privileges on the system. (CVE-2023-4004)

  - A use-after-free flaw was found in the Linux kernel's Netfilter functionality when adding a rule with     NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
    (CVE-2023-4147)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A time-of-check to time-of-use issue exists in io_uring subsystem's IORING_OP_CLOSE operation in the Linux     kernel's versions 5.6 - 5.11 (inclusive), which allows a local user to elevate their privileges to root.
    Introduced in b5dba59e0cf7e2cc4d3b3b1ac5fe81ddf21959eb, patched in     9eac1904d3364254d622bf2c771c4f85cd435fc2, backported to stable in     788d0824269bef539fe31a785b1517882eafed93. (CVE-2023-1295)

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A known cache speculation vulnerability, known as Branch History Injection (BHI) or Spectre-BHB, becomes     actual again for the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code     uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted     branches within the victim's hardware context. Once that occurs, speculation caused by the mispredicted     branches can cause cache allocation. This issue leads to obtaining information that should not be     accessible. (CVE-2023-3006)

  - A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in     the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend     upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

  - A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service. (CVE-2023-3161)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against     attackers with the stated 'When modifying the block device while it is mounted by the filesystem' access.
    (CVE-2023-34256)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

  - An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.

    bpf: Fix incorrect verifier pruning due to missing register precision taints(CVE-2023-2163)

    A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local     privilege escalation.Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a     hrtimer.We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59     (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and0e388fce7aec40992eadee654193cad345d62663     for 5.15 stable).(CVE-2023-3389)

    A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c.Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue.We recommend upgrading past     commit1240eb93f0616b21c675416516ff3d74798fdc97.(CVE-2023-3390)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c.(CVE-2023-35823)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c.(CVE-2023-35824)

    A race condition was found in the Philips SAA7134 driver in the Linux kernel. In saa7134_initdev, dev-     video_q.timeout is eventually bound to saa7134_buffer_timeout. If we remove the module or device which     will call saa7134_finidev to cleanup, there may be unfinished work. This could lead to a use-after-free     issue.(CVE-2023-3327)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information.(CVE-2023-3268)

    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation.(CVE-2023-35788)

    A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel     panic.(CVE-2023-3212)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against     attackers with the stated 'When modifying the block device while it is mounted by the filesystem'     access.(CVE-2023-34256)

    A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service problem.(CVE-2023-2985)

    A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system.(CVE-2023-2156)

    An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(fepriv-gt;sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(fepriv-gt;sem) may block the process.(CVE-2023-31084)

    In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the     drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually     an error pointer).(CVE-2023-22998)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit     0323bce598eea038714f941ce2b22541c46d488f.(CVE-2023-3776)

    A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 ('tun: tun_chr_open(): correctly initialize socket uid'), - 66b2c338adce ('tap: tap_open():
    correctly initialize socket uid'), pass 'inode-i_uid' to sock_init_data_uid() as the last parameter and     that turns out to not be accurate.(CVE-2023-4194)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation.If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability.We recommend upgrading past commit     0323bce598eea038714f941ce2b22541c46d488f.(CVE-2023-3776)

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.10.192-182.736. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-039 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    RDMA/cma: Ensure rdma_addr_cancel() happens before issuing more requests (CVE-2021-47391)

    A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

    A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c.

    Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same     transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to     cause a privilege escalation issue.

    We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

    The fix for XSA-423 added logic to Linux'es netback driver to deal witha frontend splitting a packet in a     way such that not all of the headerswould come in one piece.  Unfortunately the logic introduced     theredidn't account for the extreme case of the entire packet being splitinto as many pieces as permitted     by the protocol, yet still beingsmaller than the area that's specially dealt with to keep all     (possible)headers together.  Such an unusual packet would therefore trigger abuffer overrun in the driver.
    (CVE-2023-34319)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the     chain's owner rule can also release the objects in certain circumstances.

    We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. (CVE-2023-3777)

    A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

    An out-of-bounds read vulnerability was found in Netfilter Connection Tracking (conntrack) in the Linux     kernel. This flaw allows a remote user to disclose sensitive information via the DCCP protocol.
    (CVE-2023-39197)

    A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the     nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local     user to crash the system or potentially escalate their privileges on the system. (CVE-2023-4004)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    On an error when building a nftables rule, deactivating immediate expressions in     nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used.

    We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2. (CVE-2023-4015)

    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue. (CVE-2023-4128)

    netfilter: nf_tables: disallow rule addition to bound chain via NFTA_RULE_CHAIN_ID (CVE-2023-4147)

    A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to     achieve local privilege escalation.

    When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into     the new instance of the filter. This causes a problem when updating a filter bound to a class, as     tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the     still referenced class and allowing it to be deleted, leading to a use-after-free.

    We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8. (CVE-2023-4206)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation.

    When fw_change() is called on an existing filter, the whole tcf_result struct is always copied into the     new instance of the filter. This causes a problem when updating a filter bound to a class, as     tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the     still referenced class and allowing it to be deleted, leading to a use-after-free.

    We recommend upgrading past commit 76e42ae831991c828cffa8c37736ebfb831ad5ec. (CVE-2023-4207)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation.

    When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the     new instance of the filter. This causes a problem when updating a filter bound to a class, as     tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the     still referenced class and allowing it to be deleted, leading to a use-after-free.

    We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81. (CVE-2023-4208)

    A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation     of the file name reconstruction function, which is responsible for reading file name entries from a     directory index and merging file name parts belonging to one file into a single long file name. Since the     file name characters are copied into a stack variable, a local privileged attacker could use this flaw to     overflow the kernel stack. (CVE-2023-4273)

    A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local     privilege escalation.

    The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without     locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that     is being released by garbage collection, resulting in use-after-free.

    We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. (CVE-2023-4622)

    In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

    In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

    A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two     threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline     enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This     could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

    A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges     to trigger a deadlock and potentially crash the system. (CVE-2024-0639)
