The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000492 advisory.

    A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service.

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

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2020-121:05 advisory.

    * kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c     (CVE-2017-18595)
      * kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c (CVE-2019-19768)
      * Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause     kernel panic (CVE-2020-10711)
