{"id":"DEBIAN-CVE-2022-49133","details":"In the Linux kernel, the following vulnerability has been resolved:  drm/amdkfd: svm range restore work deadlock when process exit  kfd_process_notifier_release flush svm_range_restore_work which calls svm_range_list_lock_and_flush_work to flush deferred_list work, but if deferred_list work mmput release the last user, it will call exit_mmap -\u003e notifier_release, it is deadlock with below backtrace.  Move flush svm_range_restore_work to kfd_process_wq_release to avoid deadlock. Then svm_range_restore_work take task-\u003emm ref to avoid mm is gone while validating and mapping ranges to GPU.
