Linux kernel is vulnerable to information disclosure attacks. A local user could exploit a flaw in the inet_diag_msg_sctpaddrs_fill(), inet_diag_msg_sctpladdrs_fill(), and sctp_get_sctp_info() functions in ‘net/sctp/sctp_diag.c’ to obtain potentially sensitive information in portions of slab memory on the target system.
