  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/gud: NUL-terminate TV mode names read from the device  gud_connector_add_tv_mode() reads a buffer of fixed-size mode names from the USB device and passes pointers into it to drm_mode_create_tv_properties_legacy(), which calls strlen() on each one. Nothing guarantees the device NUL-terminates a name, so strlen() can run past the end of a slot and, for the last mode, past the end of the allocation.  Terminate each name at the end of its slot before use.",
