## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: bcmasp: fix tx_spb_ring_full() checking same slot cnt times

The loop initialised next_index from intf->tx_spb_index on every
iteration, so incr_ring() always produced the same result and only
one slot was ever tested.  Move the initialisation before the loop
so each iteration advances next_index and the function correctly
checks that cnt consecutive descriptor slots are available before
allowing a new transmission.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
