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. (NVD)
