Bluetooth: RFCOMM - Fix info leak via getsockname()
[ Upstream commit 9344a972961d1a6d2c04d9008b13617bcb6ec2ef ] The RFCOMM code fails to initialize the trailing padding byte of struct sockaddr_rc added for alignment. It that for leaks one byte kernel stack via the getsockname() syscall. Add an explicit memset(0) before filling the structure to avoid the info leak.
