This vulnerability, an out-of-bounds (OOB) access, occurs due to an insufficient check of frame length before accessing management fields within the `mt76_connac2_mac_write_txwi_80211()` function. An attacker could potentially exploit this to cause memory corruption, which may lead to system instability or a denial of service (DoS)." ],
