SUSE update for kernel-firmware

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU96619

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

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.
