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().
