Description

The Linux kernel contains a flaw that may allow a remote denial of service. The issue is triggered because of a flaw in the bounds checking process of chunk lengths and parameter lengths defined in 'include/net/sctp/sctp.h'. This might lead to attempted access of invalid memory and might result in a kernel crash and hence loss of availability for the platform.
