Description

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.
