Description
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix rxkad crypto unalignment handling Fix handling of a packet with a misaligned crypto length. Also handle non-ENOMEM errors from decryption by aborting. Further, remove the WARN_ON_ONCE() so that it can't be remotely triggered (a trace line can still be emitted).
