{"schema":"threatline.record/2","record":{"id":"CVE-2026-93234","aliases":[],"summary":"drm/gud: validate TV mode names before creating enum property","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/gud: validate TV mode names before creating enum property\n\nThe GUD protocol returns TV mode names as fixed-size\nGUD_CONNECTOR_TV_MODE_NAME_LEN entries and requires each name to be\nNUL-terminated.\n\ngud_connector_add_tv_mode() currently passes each fixed-size entry\ndirectly to drm_mode_create_tv_properties_legacy(), which eventually\nreaches drm_property_add_enum() and strlen(). If a device returns an\nentry without a terminating NUL byte, strlen() reads past the end of\nthe slot and can run beyond the allocated buffer, triggering an\nout-of-bounds read.\n\nValidate that each returned TV mode name contains a NUL terminator\nwithin its fixed-size slot before passing it to the DRM property code.\nIf a malformed entry is found, reject the device response with -EIO.\n\nThis fixes the out-of-bounds read without changing the handling of\nvalid devices, and avoids silently truncating malformed protocol data.","categories":["Operating
