high Nessus Plugin ID 158727

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0772 advisory.

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

- kernel: use-after-free in RDMA listen() (CVE-2021-4028)

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

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

Solution

Update the affected packages.
