Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0825 advisory. - 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: missing check in ioctl allows kernel memory read/write (CVE-2022-0516) - kernel: improper initialization of the flags member of the new pipe_buffer (CVE-2022-0847) - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
