CVE-2026-64242

Local denial of service via double free

Published Jul 24, 2026 · Updated Jul 24, 2026

Double free in the net2280 USB gadget driver in Linux Kernel allows local users to corrupt memory and crash the system. During failed device probing, net2280_remove() drops the embedded gadget's final reference through usb_put_gadget(), allowing gadget_release() to free its net2280 object before kfree(dev) frees the same allocation again. Exploitation requires local low-privileged access and the net2280 probe error path; the reported consequence is an unstable or unresponsive system.
