MGASA-2022-0212 - Updated kernel packages fix security vulnerabilities

Publication date: 28 May 2022
URL: https://advisories.mageia.org/MGASA-2022-0212.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-1729,
     CVE-2022-1789,
     CVE-2022-21499

This kernel update is based on upstream 5.15.43 and fixes at least the
following security issues:

A race condition in the perf subsystem allows for a local privilege
escalation. NOTE: Mageia kernels by default has disabled the perf usage
for unprivileged users, effectively rendering this vulnerability harmless
(CVE-2022-1729).

KVM: x86/mmu: fix NULL pointer dereference on guest INVPCID
(CVE-2022-1789).

Kernel could allow a remote attacker to bypass security restrictions,
caused by a lockdown break issue. By sending a specially-crafted request
using the kernel debugger, an attacker could exploit this vulnerability
to perform read and write access to kernel memory (CVE-2022-21499).

Other fixes in this update:
- ice: fix crash at allocation failure

For other upstream fixes, see the referenced changelogs.
