Notes

Title of the patch: Security update for the Linux Kernel (Live Patch 23 for SLE 12 SP4)

Description of the patch: This update for the Linux Kernel 4.12.14-95_83 fixes several issues. The following security issues were fixed: - CVE-2022-20154: Fixed a use after free due to a race condition in lock_sock_nested of sock.c. This could lead to local escalation of privilege with System execution privileges needed (bsc#1200599). - CVE-2022-21499: Reinforced the kernel lockdown feature, until now it's been trivial to break out of it with kgdb or kdb (bsc#1199426). - CVE-2022-1729: Fixed a sys_perf_event_open() race condition against self (bsc#1199507).

CVE-2022-21499 (GCVE-0-2022-21499)

Vulnerability from cvelistv5 – Published: 2022-06-09 20:15 – Updated: 2024-09-24 20:05

Summary

KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

Severity ?

6.7 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
