Description
A flaw was found in the Linux kernel's goku_udc USB gadget driver. An attacker or event triggering a USB reset interrupt before a gadget driver is bound, or after one is unbound, causes the interrupt handler to access an uninitialized driver pointer while logging the event. This flaw results in a null-pointer dereference, leading to a kernel crash and a Denial of Service (DoS).
