  "description": "In the Linux kernel, the following vulnerability has been resolved:  rxrpc: Fix use of wrong skb when comparing queued RESP challenge serial  In rxrpc_post_response(), the code should be comparing the challenge serial number from the cached response before deciding to switch to a newer response, but looks at the newer packet private data instead, rendering the comparison always false.  Fix this by switching to look at the older packet.  Fix further[1] to substitute the new packet in place of the old one if newer and also to release whichever we don\u0027t use.",
