VUL-0: CVE-2022-48843: kernel: drm/vrr: Set VRR capable prop only if it is attached to connector
Last modified: 2024-07-17 13:24:11 UTC
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. So if the driver tries to call drm core set prop function without it being attached that causes NULL dereference.
