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

wifi: rtw89: add bounds check on firmware mac_id in link lookup

The mac_id field in RX descriptors is 8 bits wide (0-255), but assoc_link_on_macid[] has only RTW89_MAX_MAC_ID_NUM (128) entries. While the driver currently assigns mac_id values below 128, the descriptor value comes from firmware and is not validated before use as an array index. Add a defensive bounds check in rtw89_assoc_link_rcu_dereference() to guard against out-of-range firmware values.
