GHSA-f37v-5r8j-33m9 PUBLISHED CVSS 5.5 MEDIUM

Record from GitHub Advisory Database · Published April 22, 2026

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.
