NVDhttps://nvd.nist.gov/vuln/detail/CVE-2011-1573
CWEhttps://cwe.mitre.org/data/definitions/682.html

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.

Weakness

The product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management.
