In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Stop job scheduling across aie2_release_resource()

Running jobs on a hardware context while it is in the process of
releasing resources can lead to use-after-free and crashes.

Fix this by stopping job scheduling before calling
aie2_release_resource() and restarting it after the release completes.
Additionally, aie2_sched_job_run() now checks whether the hardware
context is still active.
