    Описание

    Оригинално описание

    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->gadget before acquiring dev->lock, but dev->state 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->ops->ioctl. Read dev->gadget while holding dev->lock so that the gadget pointer and device state are sampled consistently.
