Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2025-11-17 15:30In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix locking order in ivpu_job_submit
Fix deadlock in job submission and abort handling. When a thread aborts currently executing jobs due to a fault, it first locks the global lock protecting submitted_jobs (#1).
After the last job is destroyed, it proceeds to release the related context and locks file_priv (#2). Meanwhile, in the job submission thread, the file_priv lock (#2) is taken first, and then the submitted_jobs lock (#1) is obtained when a job is added to the submitted jobs list.

---- ----
(for example due to a fault) (jobs submissions keep coming)
lock(&vdev->submitted_jobs_lock) #1 ivpu_jobs_abort_all() job_destroy() lock(&file_priv->lock) #2 lock(&vdev->submitted_jobs_lock) #1 file_priv_release() lock(&vdev->context_list_lock) lock(&file_priv->lock) #2
This order of locking causes a deadlock. To resolve this issue, change the order of locking in ivpu_job_submit().
