MEDIUM

Linux Kernel < 2.6.34 - Denial of Service via SCTP Chunk Length Calculation

Title source: llm
STIX 2.1

Description

net/sctp/sm_make_chunk.c in the Linux kernel before 2.6.34, when addip_enable and auth_enable are used, does not consider the amount of zero padding during calculation of chunk lengths for (1) INIT and (2) INIT ACK chunks, which allows remote attackers to cause a denial of service (OOPS) via crafted packet data.
