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.
Affected configurations
• linux linux kernel (>= 2.6.22 < 6.6.140)
• linux linux kernel (>= 6.7 < 6.12.86)
• linux linux kernel (>= 6.13 < 6.18.27)
