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-2022:0825 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

The following packages have been upgraded to a later upstream version: kernel (4.18.0). (BZ#2036888)

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: missing check in ioctl allows kernel memory read/write (CVE-2022-0516)

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