CVE-2026-31518

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