Details

In the Linux kernel, the following vulnerability has been resolved:

drm/tests: shmem: Hold reservation lock around purge

Acquire and release the GEM object's reservation lock around calls to the object's purge operation. The tests use drm_gem_shmem_purge_locked(), which led to errors such as show below.

[ 58.709128] WARNING: CPU: 1 PID: 1354 at drivers/gpu/drm/drm_gem_shmem_helper.c:515 drm_gem_shmem_purge_locked+0x51c/0x740

Only export the new helper drm_gem_shmem_purge() for Kunit tests. This is not an interface for regular drivers.

Severity

5.5 (Medium)
