{"id":"AZL-104772","summary":"CVE-2026-98148 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/gud: validate GUD_ROTATION_0 is present in supported rotations\n\nThe rotation argument to drm_plane_create_rotation_property() is set to\nDRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as\nthe supported_rotations argument. The driver never validates that\nGUD_ROTATION_0 is present, so a device that omits it from its\nGUD_PROPERTY_ROTATION triggers the\nWARN_ON(rotation & ~supported_rotations) in\ndrm_plane_create_rotation_property()\n\nFix this by skipping the creation of rotation property if the device\ndoesn't have the GUD_ROTATION_0 bit","modified":"2026-09-29T05:37:47Z","published":"2026-09-25T11:17:46Z","upstream":["CVE-2026-98148"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98148"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104772.json"}}],"schema_version":"1.9.0"}
