Impact
In the Linux kernel’s DRM GUD driver, the rotation property for a plane is created with a rotation value of DRM_MODE_ROTATE_0. The driver receives a bitmask of supported rotations from the device, but it never verifies that the GUD_ROTATION_0 flag is included. If a device omits this flag, the check WARN_ON(rotation & ~supported_rotations) in drm_plane_create_rotation_property() fires, resulting in a warning message in the kernel log. The patch removes the creation of the rotation property when the required flag is not present, preventing the warning.
Affected Systems
All Linux kernel releases that contain the DRM GUD component are affected. The issue is tied to the generic DRM subsystem and is not limited to a specific vendor or kernel series. Devices that advertise GUD_PROPERTY_ROTATION without the GUD_ROTATION_0 flag will trigger the warning. Administrators should verify that their running kernel includes the patch that suppresses the faulty check.
Risk and Exploitability
The vulnerability does not provide a direct security impact beyond the appearance of a warning in the kernel log. No CVSS score is supplied, and the issue is not listed in CISA’s KEV catalog. Because it requires the device to omit the GUD_ROTATION_0 flag, the only observable effect is log noise or a misconfiguration. No privilege escalation or remote code execution is possible from the information available.
