Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the drm/vrr component of the Linux kernel. It occurs when the driver attempts to call the drm core set prop function without being attached to a connector, resulting in a NULL dereference. This can lead to a denial of service. The VRR capable property is not attached by default to the connector and is only attached if VRR is supported.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
