What this means
The Linux kernel has a vulnerability where the kfd_smi_ev_enabled() function skips the suser privilege check, allowing any /dev/kfd user in the render group to monitor all GPU workloads. This affects Linux kernel versions starting from 5.9. The vulnerability is an information leak.

What to do
Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.
No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description
Read the full publisher 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.
