CVE-2026-98051
Published: September 29, 2026Last modified: September 29, 2026
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.
