  "details": "In the Linux kernel, the following vulnerability has been resolved:  USB: gadget: fix NULL pointer dereference in gadget_dev_ioctl()  gadget_dev_ioctl() reads dev-\u003egadget before acquiring dev-\u003elock, but dev-\u003estate is checked after acquiring the lock. Therefore a concurrent bind can change the device state between these operations, which can leave ioctl with a stale NULL gadget pointer and causing a NULL pointer dereference at gadget-\u003eops-\u003eioctl.  Read dev-\u003egadget while holding dev-\u003elock so that the gadget pointer and device state are sampled consistently.",
