CVE-2026-97422

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: fix SMI event cross-process information leak

kfd smi ev enabled() skips the suser privilege check when pid=0. PROCESS START, PROCESS END, and VMFAULT events are emitted with pid=0 while carrying another process's PID and command name, so any /dev/kfd user in the render group can monitor all GPU workloads.

Pass the target process PID into kfd smi event add() for these events so the existing per-client filter restricts delivery to the owning process or CAP SYS ADMIN subscribers.
