CVE-2026-31518

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> esp: fix skb leak with espintcp and async crypto<br /> <br /> When the TX queue for espintcp is full, esp_output_tail_tcp will<br /> return an error and not free the skb, because with synchronous crypto,<br /> the common xfrm output code will drop the packet for us.<br /> <br /> With async crypto (esp_output_done), we need to drop the skb when<br /> esp_output_tail_tcp returns an error.
