Deskripsi CVE
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.
