CVE-2025-71296

Estado: AnalizadaMedia (5.5)—

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.

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