Description
In the Linux kernel, the following vulnerability has been resolved:
drm/syncobj: Fix memory leak in drm_syncobj_find_fence()
Commit 18226ba52159 ("drm/syncobj: reject invalid flags in
drm_syncobj_find_fence") forgot to take into account the fact that
drm_syncobj_find() takes a reference to syncobj and returns early
without dropping the reference, leading to memory leaks.
