Details

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.

[ 58.339389] WARNING: CPU: 1 PID: 1352 at drivers/gpu/drm/drm_gem_shmem_helper.c:499 drm_gem_shmem_madvise_locked+0xde/0x140

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

Severity

5.5 (Medium)
