Doc Text:	A flaw was found in the rtw88 Wi-Fi driver of the Linux kernel. This issue occurs because the rtw_txq_push_skb() function fails to free a socket buffer (skb) when an error occurs during transmission. This oversight can lead to a memory leak, potentially impacting system stability and performance over time.	Story Points:	---

Description OSIDB Bzimport 2026-09-11 23:40:46 UTC

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

wifi: rtw88: Fix potential memory leak in rtw_txq_push_skb()

The skb passed to the rtw_hci_tx_write() is expected to be freed when
the function fails, but the error path in rtw_txq_push_skb() does not
free the skb before returning. This can lead to a memory leak in
rtw_txq_push() where a dequeued skb is passed to rtw_txq_push_skb().
