{"schema":"threatline.record/2","record":{"id":"CVE-2026-97422","aliases":[],"summary":"drm/amdkfd: fix SMI event cross-process information leak","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: fix SMI event cross-process information leak\n\nkfd_smi_ev_enabled() skips the suser privilege check when pid=0.\nPROCESS_START, PROCESS_END, and VMFAULT events are emitted with\npid=0 while carrying another process's PID and command name, so any\n/dev/kfd user in the render group can monitor all GPU workloads.\n\nPass the target process PID into kfd_smi_event_add() for these events\nso the existing per-client filter restricts delivery to the owning\nprocess or CAP_SYS_ADMIN subscribers.","categories":["Operating
