Executive Summary

This vulnerability involves improper validation of input values in AMD Power Management Firmware (PMFW). A local attacker could exploit this by passing unsanitized input, triggering a bit-shift operation with an out-of-range value. This may cause an immediate system reboot, resulting in a denial of service.

Detection Guidance

Detection involves checking firmware versions against affected AMD EPYC processors. Use system management tools like dmidecode or BIOS tools to verify PMFW versions. Monitor system logs for unexpected reboots or crashes.

Impact Analysis

The vulnerability can lead to a system crash or denial of service, causing unexpected reboots and disrupting normal operations. It requires local access to exploit, limiting the risk to systems with physical or authenticated remote access.

Mitigation Strategies

Update to the latest Platform Initialization (PI) firmware versions for AMD EPYC 9005 Series or EPYC Embedded 9005 Series. Contact your OEM for BIOS updates if not directly available. Disable debug message access if possible.
