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

State: Published
Severity: Not scored

Description

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.
