Description OSIDB Bzimport 2026-05-08 15:02:12 UTC
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix runtime suspend deadlock when there is pending job

The runtime suspend callback drains the running job workqueue before
suspending the device. If a job is still executing and calls
pm_runtime_resume_and_get(), it can deadlock with the runtime suspend
path.

Fix this by moving pm_runtime_resume_and_get() from the job execution
routine to the job submission routine, ensuring the device is resumed
before the job is queued and avoiding the deadlock during runtime
suspend.
