CVE-2026-68447

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the drm/amdkfd component where the CRIU checkpoint process copies the MQD control stack using the cp hqd cntl stack size value from hardware without bounding it to the allocated BO (Buffer Object) region. If the hardware field exceeds the queue's control stack allocation, the memcpy() function reads beyond the BO into adjacent GTT (Graphics Translation Table) memory, which can lead to the leakage of kernel data to userspace.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
