Description
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix out-of-bounds tid_data access in BA notif mvmsta->tid_data was indexed by the TFD loop counter 'i' instead of the actual TID value 'tid'. This writes lq_color into a random tid_data slot unrelated to the BA entry. Since multi-TID blockack is not really in use, 'i' was always 0 and no harm was done. Add a out-of-bound check before accessing the array.
