A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: fix GEM object leak on ENOMEM in userptr ioctl

When amdgpu_hmm_range_alloc() fails amdgpu_gem_userptr_ioctl() returns -ENOMEM right away and skips the cleanup every other error path goes through. The GEM object, the bo->parent reference on the VM root and the MMU notifier registration are all left behind.

Use release_object here, not user_pages_done, range is still NULL at this point.

(cherry picked from commit bbe739e407a542073ec1a7872b14843566b4919e)
