CVE-2026-80941

CVE-2026-80941 affects the Linux kernel wifi: rtw88 driver. The root cause is in rtw_txq_push_skb() : when the skb passed to rtw_hci_tx_write() fails, the error path does not free the skb before returning. This leads to a potential memory leak in rtw_txq_push() , where a dequeued skb is passed to...
