CVE-2025-71301
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/tests: shmem: Hold reservation lock around vmap/vunmap Acquire and release the GEM object's reservation lock around vmap and vunmap operations. The tests use vmap_locked, which led to errors such as show below.
