Description
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.
