Linux SCTP receive buffer deadlock denial of service
|linux-sctp-receive-dos (26433)||Medium Risk|
Linux kernel SCTP (lksctp) could allow a remote attacker to cause a denial of service, caused by a deadlock error in the receive buffer. A remote attacker could exploit this vulnerability by sending a large number of small messages to cause a denial of service.
