[PATCH] caif: Add sockaddr length check before accessing sa_family in connect handler

2017-06-13 Thread Mateusz Jurczyk
Verify that the caller-provided sockaddr structure is large enough to contain the sa_family field, before accessing it in the connect() handler of the AF_CAIF socket. Since the syscall doesn't enforce a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long)
