Description

The Linux kernel contains a flaw that may allow a remote denial of service. The issue is triggered when a SCTP packet is received that contains at least the first two fragments of a bundled message. The handling of data buffers in the kernel leads to a pointer self reference, which will lead to an infinite recursion resulting in loss of availability for the platform.
