Mateusz Jurczyk 0fc0fad077 af_unix: Add sockaddr length checks before accessing sa_family in bind and connect handlers ... [ Upstream commit defbcf2decc903a28d8398aa477b6881e711e3ea ] Verify that the caller-provided sockaddr structure is large enough to contain the sa_family field, before accessing it in bind() and connect() handlers of the AF_UNIX socket. Since neither syscall enforces a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long) result in operating on uninitialized memory while referencing .sa_family.
