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

    An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free.(CVE-2022-45886)

    In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This     could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.(CVE-2023-21255)

    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)

    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 flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal     kernel information.(CVE-2023-3567)

    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)

    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)

    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)

    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 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 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)

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

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6260-1 advisory.

    It was discovered that the NTFS file system implementation in the Linux kernel did not properly check     buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker     could possibly use this to expose sensitive information (kernel memory). (CVE-2022-48502)

    Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux     kernel did not properly perform permission checks in certain situations. A local attacker could possibly     use this to gain elevated privileges. (CVE-2023-2640)

    It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory     in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause     a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090)

    Mingi Cho discovered that the netfilter subsystem in the Linux kernel did not properly validate the status     of a nft chain while performing a lookup by id, leading to a use-after-free vulnerability. An attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-31248)

    It was discovered that the Ricoh R5C592 MemoryStick card reader driver in the Linux kernel contained a     race condition during module unload, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3141)

    Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did     not properly perform permission checks in certain situations. A local attacker could possibly use this to     gain elevated privileges. (CVE-2023-32629)

    Querijn Voet discovered that a race condition existed in the io_uring subsystem in the Linux kernel,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-3389)

    It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error     conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-3390)

    Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain     pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35001)
