In the Linux kernel, the following vulnerability has been resolved:

rxrpc: Fix conn-level packet handling to unshare RESPONSE packets

The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the sk_buff may be shared with a packet sniffer, which would lead to the sniffer seeing an apparently corrupt packet (actually decrypted).

Fix this by handing a copy of the packet off to the specific security handler if the packet was cloned.
