CVE-2026-89817
Description
AI Translation Available
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.
