CVE-2026-64346

CVE-2026-64346 is a Use-After-Free (UAF) in the Linux kernel's USB gadget UDC subsystem. A race condition allows usb_del_gadget() to free the udc management structure (e.g., via a mode-switch workqueue) while gadget_match_driver() concurrently accesses it through configfs, triggering a NULL point...

CVE-2026-64346 usb: gadget: udc: Fix use-after-free in gadget_match_driver

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: udc: Fix use-after-free in gadgetmatchdriver The udc structure acts as the management structure for the gadget, but their lifecycles are decoupled. A race condition exists where usbdelgadget frees the udc memory e.g....
