Linux SCTP ECNE CLOSED state chunk denial of service
|linux-sctp-ecne-chunk-dos (26430)||Medium Risk|
Linux kernel SCTP (lksctp) could allow a remote attacker to cause a denial of service, caused by improper handling of ECNE chunks that are received in the CLOSED state. A remote attacker could exploit this vulnerability to cause a kernel panic.
Denial of Service
