CVE-2026-64345

The CVE-2026-64345 issue affects the Linux kernel USB gadget f_printer driver. printer_open() increments dev->kref even when an open fails with -EBUSY, causing a reference leak because VFS does not call ->release() for failed opens. The fix moves the kref_get() into the successful-open path...

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....

CVE-2026-64346

Summary: CVE-2026-64346 affects the Linux kernel USB gadget udc path. A race condition can occur when the udc (managing gadget state) is freed by usb_del_gadget() while gadget_match_driver() may still access the freed udc (e.g., via configfs). This Use-After-Free can trigger a NULL pointer derefe...
