Description
A vulnerability in the Linux kernel's rxrpc connection-level packet handling was fixed to prevent shared RESPONSE packets from being decrypted in place, which could cause packet sniffers to see corrupted data. The fix involves copying the packet for the security handler when the packet was cloned.
