CVE-ID: CVE-2023-39368

CWE-ID: CWE-693 - Protection Mechanism Failure

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient implementation of security measures in the bus lock regulator mechanism. A remote attacker can trick the victim to open a specially crafted file and perform a denial of service (DoS) attack.

Mitigation

Update the affected package ucode-intel to the latest version.
