Summary
Red Hat Security Advisory: kpatch-patch security update
Notes
Topic
An update for kpatch-patch is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.
Security Fix(es):
* 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.

In most circumstances, the TIPC kernel module will be unable to be unloaded while any network interfaces are active and the protocol is in use.\n\nIf the system requires this module to work correctly, this mitigation may not be suitable.",
