CVE-2026-31606 usb: gadget: f_hid: don't call cdev_init while cdev in use

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fhid: don't call cdevinit while cdev in use When calling unbind, then bind again, cdevinit reinitialized the cdev, even though there may still be references to it. That's the case when the /dev/hidg device is still...

CVE-2026-31606

The CVE-2026-31606 issue affects the Linux kernel USB HID gadget driver. When a /dev/hidg* device is still open, unbind/bind operations can reinitialize a live cdev, which is unsafe and can crash the system. The core problem is calling cdev_init while the cdev is still in use; the fix is to alloc...
