Linux kernel sctp_getsockopt_local_addrs_old() denial of service
| linux-kernel-sctpgetsockopt-dos (43559) |  Low Risk |
Description:
The Linux kernel is vulnerable to a denial of service, caused by an integer overflow in the sctp_getsockopt_local_addrs_old function in net/sctp/socket.c. A local attacker could exploit this vulnerability by setting an overly large addr_num field in an sctp_getaddrs_old data structure to consume all available resources and cause the system to stop responding.
