MediumCVSS 4.7/10Last modified Aug 4, 2026

Description

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

drm/virtio: Fix GEM handle creation UAF

Userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if we dereference the object after dropping the handle's reference. For that reason, dropping the handle's reference must be done *after* we are done dereferencing the object.
