CVE-2010-4526 at MITRE

Description

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

Note from the SUSE Security Team

This issue affects SUSE Linux products with kernels 2.6.11 and above. It seems however only exploitable to cause a denial of service, if an attacker has control over network availability. It also requires SCTP being configured and used.
