From VID-B2B83761-6A09-11EA-92AB-00163E433440:

Problem Description:

The driver-specific ioctl(2) command handlers in ixl(4) failed to

check whether the caller has sufficient privileges to perform the

corresponding operation.

Impact:

The ixl(4) handler permits unprivileged users to trigger updates to

the device's non-volatile memory (NVM).
