CVE-2022-48794

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: ieee802154: at86rf230: Stop leaking skb&amp;#39;s<br /> <br /> Upon error the ieee802154_xmit_complete() helper is not called. Only<br /> ieee802154_wake_queue() is called manually. In the Tx case we then leak<br /> the skb structure.<br /> <br /> Free the skb structure upon error before returning when appropriate.<br /> <br /> As the &amp;#39;is_tx = 0&amp;#39; cannot be moved in the complete handler because of a<br /> possible race between the delay in switching to STATE_RX_AACK_ON and a<br /> new interrupt, we introduce an intermediate &amp;#39;was_tx&amp;#39; boolean just for<br /> this purpose.<br /> <br /> There is no Fixes tag applying here, many changes have been made on this<br /> area and the issue kind of always existed.
