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