Summary
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix rxrpc_peer leak in rxrpc_look_up_bundle() Need to call rxrpc_put_peer() for bundle candidate before kfree() as it holds a ref to rxrpc_peer. [DH: v2: Changed to abstract out the bundle freeing code into a function]
