CVE-2024-26715

Kernel crash via DWC3 gadget suspend race

Published Apr 3, 2024 · Updated May 23, 2026

NULL pointer dereference in Linux DWC3 gadget handling allows local users to crash the kernel via repeated USB reconnects. The dwc3_gadget_suspend path checks gadget_driver while a concurrent gadget unbind clears it, then dwc3_disconnect_gadget dereferences the cleared pointer. Reachability requires a system using the DWC3 USB gadget controller and overlap between suspend and driver unbind during repeated disconnect-and-reconnect activity.
