Description

The Linux kernel contains a flaw that may allow a remote denial of service. The issue is triggered because of a flow in the kernel's Stream Control Transmission Protocol (SCTP). When a crafted 'ECNE chunk' SCTP is sent to the system, an incorrect state table entry might be created when the packet is received in closed state. This might result in a kernel panic and hence loss of availability for the platform.
