CVE-2026-98051

Summary
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.
