In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix leak of released call in recvmsg(MSG_PEEK)
Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released
call if MSG_PEEK is in force (the function holds a ref on the call
irrespective of whether MSG_PEEK is specified or not).
