DescriptionIn the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Properly acquire queue buffers in CRIU restore When kfd_queue_acquire_buffers() was split off from set_queue_properties_from_user(), set_queue_properties_from_criu() was missed. Thus, set_queue_properties_from_criu() is not filling out the buffer fields of queue_properties, which can come up when subsequent code expects them to be non-null. Add the proper call to kfd_queue_acquire_buffers(), and also use the right cast types in set_queue_properties_from_criu() (which were missed at the same time) (cherry picked from commit 88ed96abbbe27b70193544fbc1ee06448c274714)
