AI-suggested
A patch is available and fixed versions include linux kernel releases 6.8.0-1064.67~22.04.1 and later variants as listed. Users should upgrade to these fixed kernel versions to remediate the issue. No additional mitigations are required as the fix properly handles the NULL pointer condition and propagates errors to userspace.
Description
A NULL pointer dereference vulnerability in the Linux kernel's drm/amdkfd subsystem was fixed. The flaw occurs when a userspace call provides a non-zero number of queues but a NULL queue ID array pointer, leading to a kernel panic due to improper NULL checks. This issue affects certain Linux kernel versions and has been resolved in later fixed releases.
