The remote OracleVM system is missing necessary patches to address security updates:

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way     user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()     together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),     hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their     privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)

  - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in     the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could     potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.
    (CVE-2021-45095)

  - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file. (CVE-2021-45868)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

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

Tenable has extracted the preceding description block directly from the Oracle Linux 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 remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0362-1 advisory.

    The SUSE Linux Enterprise 12 SP3 LTSS kernel was updated to receive various security and bugfixes.


    The following security bugs were fixed:

    - CVE-2018-25020: Fixed an overflow in the BPF subsystem due to a mishandling of a long jump over an     instruction sequence where inner instructions require substantial expansions into multiple BPF     instructions. This affects kernel/bpf/core.c and net/core/filter.c (bnc#1193575).
    - CVE-2019-0136: Fixed insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver     that may have allowed an unauthenticated user to potentially enable denial of service via adjacent access     (bnc#1193157).
    - CVE-2020-35519: Fixed out-of-bounds memory access in x25_bind in net/x25/af_x25.c. A bounds check     failure allowed a local attacker with a user account on the system to gain access to out-of-bounds memory,     leading to a system crash or a leak of internal kernel information (bnc#1183696).
    - CVE-2021-0935: Fixed possible out of bounds write in ip6_xmit of ip6_output.c due to a use after free.
    This could lead to local escalation of privilege with System execution privileges needed. User interaction     is not needed for exploitation (bnc#1192032).
    - CVE-2021-28711: Fixed issue with xen/blkfront to harden blkfront against event channel storms (XSA-391)     (bsc#1193440).
    - CVE-2021-28712: Fixed issue with xen/netfront to harden netfront against event channel storms (XSA-391)     (bsc#1193440).
    - CVE-2021-28713: Fixed issue with xen/console to harden hvc_xen against event channel storms (XSA-391)     (bsc#1193440).
    - CVE-2021-28715: Fixed issue with xen/netback to do not queue unlimited number of packages (XSA-392)     (bsc#1193442).

      CVE-2023-1074:
      A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service.

      CVE-2023-1076:
      A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters.

      CVE-2023-1095:
      In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free     the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a     list -- the list head is all zeroes, this results in a NULL pointer dereference.

      CVE-2023-1118:
      A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in     the way user detaching rc device. A local user could use this flaw to crash the system or potentially     escalate their privileges on the system.

      CVE-2023-1281:

      In the Linux kernel before 5.17, drivers/phy/tegra/xusb.c mishandles the tegra_xusb_find_port_node     return value. Callers expect NULL in the error case, but an error pointer is used.

      CVE-2023-23004:
      In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table     return value (expects it to be NULL in the error case, whereas it is actually an error pointer).

      CVE-2023-23454:
      cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results).

      CVE-2023-23455:
      atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a     denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT     condition rather than valid classification results).

An update of the linux package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1021 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2022-36123:
    The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This     allows Xen PV guest OS users to cause a denial of service or gain privileges.

    CVE-2022-32250:
    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free.

    CVE-2022-28390:
    ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.

    CVE-2022-28388:
    usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free.

    CVE-2022-28356:
    In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c.

    CVE-2022-26966:
    An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to     obtain sensitive information from heap memory via crafted frame lengths from a device.

    CVE-2022-2586:
    A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in     the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the     time of table deletion, possibly leading to local privilege escalation.

    CVE-2022-2153:
    A flaw was found in the Linux kernels KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service.

    CVE-2022-21505:
    It was discovered that the Integrity Measurement Architecture (IMA) implementation in the Linux kernel did     not properly enforce policy in certain conditions. A privileged attacker could use this to bypass Kernel     lockdown restrictions.

    CVE-2022-21499:
    KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and     Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

    CVE-2022-20154:
    In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead     to local escalation of privilege with System execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream     kernel

    CVE-2022-1789:
    With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.

    CVE-2022-1679:
    A use-after-free flaw was found in the Linux kernels Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system.

    CVE-2022-1462:
    An out-of-bounds read flaw was found in the Linux kernels TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory.

    CVE-2022-1353:
    A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information.

    CVE-2022-1198:
    A use-after-free vulnerabilitity was discovered in drivers/net/hamradio/6pack.c of linux that allows an     attacker to crash linux kernel by simulating ax25 device using 6pack driver from user space.

    CVE-2022-1055:
    A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain     privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past     commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5

    CVE-2022-1016:
    A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle /'return/' with proper preconditions, as it can lead to a     kernel information leak problem caused by a local, unprivileged attacker.

    CVE-2022-0492:
    A vulnerability was found in the Linux kernels cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.

    CVE-2022-0435:
    A stack overflow flaw was found in the Linux kernel/'s TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network.

    CVE-2022-0185:
    A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem     Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in     case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local     user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to     legacy handling) could use this flaw to escalate their privileges on the system.

    CVE-2021-45095:
    pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.

    CVE-2021-43976:
    In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).

    CVE-2021-33655:
    When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds.

    CVE-2021-28715:
    Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record     relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]     Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in     its RX queue ring page and the next package would require more than one free slot, which may be the case     when using GSO, XDP, or software hashing. (CVE-2021-28714)

    CVE-2020-28374:
    In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking     in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal     in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker     has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are     proxied via an attacker-selected backstore.
