Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the drm/virtio component of the Linux kernel, where userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if the object is dereferenced after dropping the handle's reference. This can potentially impact confidentiality, integrity, and availability.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
