CVE-2022-48843
Linux Kernel - Dynamic Random Access Memory NULL Pointer Dereference Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: drm/vrr: Set VRR capable prop only if it is attached to connector VRR capable property is not attached by default to the connector It is attached only if VRR is supported.
