CVE-2026-97429Hinoki check available

Unspecified impact via concurrent KFD queue destruction

Published Sep 24, 2026 · Updated Sep 24, 2026

A use-after-free in Linux before 6.12.111 and before 6.18.53 allows local users with KFD access to cause an unspecified impact. wait_on_destroy_queue drops the device-queue and process locks while awaiting queue resume, so a concurrent destroy can free the queue still held by the waiting path. Reachability requires an enabled KFD debug trap, a suspended queue, and overlapping destruction attempts; the published patch does not specify a resulting security consequence.
