Description OSIDB Bzimport 2024-10-21 21:02:22 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/shmem-helper: Remove errant put in error path

drm_gem_shmem_mmap() doesn't own this reference, resulting in the GEM
object getting prematurely freed leading to a later use-after-free.
