CVE-2026-98148

Status: Undergoing AnalysisUnscored—

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

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
