In the Linux kernel, the following vulnerability has been resolved:
drm/tests: shmem: Hold reservation lock around madvise
Acquire and release the GEM object's reservation lock around calls to the object's madvide operation. The tests use drm_gem_shmem_madvise_locked(), which led to errors such as show below.
