DEBIAN-CVE-2026-80941

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Fix potential memory leak in rtwtxqpushskb The skb passed to the rtwhcitxwrite is expected to be freed when the function fails, but the error path in rtwtxqpushskb does not free the skb before returning. This can lea...

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...
