CVE-2026-97422

Estado: RecibidaSin puntuar—

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.
