The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0819 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: improper initialization of the flags member of the new pipe_buffer (CVE-2022-0847)

    * kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

    * kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container     breakout (CVE-2021-4154)

    * kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

    * kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)

    * kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492)

    * kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * kernel symbol '__rt_mutex_init' is exported GPL-only in kernel 4.18.0-348.2.1.rt7.132.el8_5 (BZ#2038423)

    * kernel-rt: update RT source tree to the RHEL-8.5.z3 source tree (BZ#2045589)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
