CVE-2026-98148

5.5 medium Analyzed
NVD · CVE.org

In the Linux kernel, the following vulnerability has been resolved: drm/gud: validate GUD_ROTATION_0 is present in supported rotations The rotation argument to drm_plane_create_rotation_property() is set to DRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as the supported_rotations argument. The driver never validates that GUD_ROTATION_0 is present, so a device that omits it from its GUD_PROPERTY_ROTATION triggers the WARN_ON(rotation & ~supported_rotations) in drm_plane_create_rotation_property() Fix this by skipping the creation of rotation property if the device doesn't have the GUD_ROTATION_0 bit
