CVE-2026-45988

Description

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix re-decryption of RESPONSE packets If a RESPONSE packet gets a temporary failure during processing, it may end up in a partially decrypted state - and then get requeued for a retry. Fix this by just discarding the packet; we will send another CHALLENGE packet and thereby elicit a further response. Similarly, discard an incoming CHALLENGE packet if we get an error whilst generating a RESPONSE; the server will send another CHALLENGE.
