SUSE update for the Linux Kernel (Live Patch 13 for SLE 15 SP3)

1) Stack-based buffer overflow

EUVDB-ID: #VU61216

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-0435

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the Linux kernel networking module for the Transparent Inter-Process Communication (TIPC) protocol. A remote unauthenticated attacker can send specially crafted traffic to the system, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the TIPC bearer is set up.

Mitigation

Update the affected package the Linux Kernel (Live Patch 13 for SLE 15 SP3) to the latest version.
