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

wifi: mt76: Fix possible oob access in mt76_connac2_mac_write_txwi_80211()

Check frame length before accessing the mgmt fields in mt76_connac2_mac_write_txwi_80211 in order to avoid a possible oob access.

[fix check to also cover mgmt->u.action.u.addba_req.capab, correct Fixes tag]
