"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2022:14905-1 advisory.

  - Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may
    allow an unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2019-0136)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a
    certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could
    happen if removing device (that is not common to remove video card physically without power-off, but same
    happens if unbind the driver). (CVE-2020-27820)

  - A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may
    cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl
    (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. (CVE-2021-3753)

  - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size
    increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS
    filesystem otherwise not accessible to them. (CVE-2021-4155)

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

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may
    allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an
    authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A vulnerability was found in the Linux kernel's 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-2022-0492)

  - 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.");
