Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-05-14 21:30In 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.
