In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: Fix WARN_ON(lock->magic != lock) error
psb_gem_unpin() calls dma_resv_lock() but the underlying ww_mutex gets destroyed by drm_gem_object_release() move the drm_gem_object_release() call in psb_gem_free_object() to after the unpin to fix the below warning:
