device\n\ngud_connector_add_tv_mode() reads a buffer of fixed-size mode names from\nthe USB device and passes pointers into it to\ndrm_mode_create_tv_properties_legacy(), which calls strlen() on each one.\nNothing guarantees the device NUL-terminates a name, so strlen() can run\npast the end of a slot and, for the last mode, past the end of the\nallocation.\n\nTerminate each name at the end of its slot before use.","state":0,"publishedAt":"2026-09-16T10:30:49.977+00:00","modifiedAt":"2026-10-19T08:53:11.379+00:00","affected":[{"ecosystem":"Vendor
