Details

A kernel data leak due to an out-of-bound read was found in the Linux kernel in inetdiagmsgsctp{,l}addrfill() and sctpgetsctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace.
