{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix re-decryption of RESPONSE packets\n\nIf a RESPONSE packet gets a temporary failure during processing, it may end\nup in a partially decrypted state - and then get requeued for a retry.\n\nFix this by just discarding the packet; we will send another CHALLENGE\npacket and thereby elicit a further response.  Similarly, discard an\nincoming CHALLENGE packet if we get an error whilst generating a RESPONSE;\nthe server will send another CHALLENGE.",
