Summary
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 -> 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->mm ref to avoid mm is
gone while validating and mapping ranges to GPU.
Workqueue: events svm_range_deferred_list_work [amdgpu]
