"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple
vulnerabilities as referenced in the SUSE-SU-2023:0768-1 advisory.

  - 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)

  - A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from
    the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length
    heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary
    code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged
    code on the target system to exploit this vulnerability. (CVE-2022-2991)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in
    drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128
    (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing
    a denial of service(DoS). (CVE-2022-36280)

  - A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c
    in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a
    local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
    (CVE-2022-38096)

  - A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing
    sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw
    to potentially crash the system causing a denial of service. (CVE-2022-4129)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The
    ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL
    MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the
    TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to
    the prctl syscall. The patch that added the support for the conditional mitigation via prctl
    (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit
    a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race
    problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race
    condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was
    found in the way user can guess location of exception stack(s) or other important data. A local user could
    use this flaw to get access to some important data with expected location in memory. (CVE-2023-0597)

  - 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-2023-1118)

  - In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an
    integer overflow in an addition. (CVE-2023-23559)

  - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure
    (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)
