SUSE update for kernel-firmware

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU96619

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-31315

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper validation in a model specific register (MSR). A malicious application with ring0 access can modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.

Mitigation

Update the affected package kernel-firmware to the latest version.
