Sources and claim methodology

Upstream source description

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().
