Description

In the Linux kernel, the following vulnerability has been resolved:  rxrpc: reject undecryptable rxkad response tickets  rxkad_decrypt_ticket() decrypts the RXKAD response ticket and then parses the buffer as plaintext without checking whether crypto_skcipher_decrypt() succeeded.  A malformed RESPONSE can therefore use a non-block-aligned ticket length, make the decrypt operation fail, and still drive the ticket parser with attacker-controlled bytes.  Check the decrypt result and abort the connection with RXKADBADTICKET when ticket decryption fails.
