Summary
In the Linux kernel, the following vulnerability has been resolved:
eth: fbnic: unlink NAPIs from queues on error to open
CI hit a UaF in fbnic in the AF_XDP portion of the queues.py test.
The UaF is in the __sk_mark_napi_id_once() call in xsk_bind(),
NAPI has been freed. Looks like the device failed to open earlier,
and we lack clearing the NAPI pointer from the queue.
