0th percentile - higher than 0% of all known CVEs

Summary

A race condition in the MxGPU-Virtualization driver’s ioctl path caused by concurrent unsynchronized access to the global variable amdgv_cmd in an unlocked ioctl handler could be exploited to trigger a heap-based buffer overflow.

Risk Assessment

An attacker may cause a denial-of-service within the vulnerable system context, leading to crash or instability.

Recommendation

Apply AMD MxGPU-Virtualization driver updates that fix the race condition, and restrict access to the ioctl interface.
