kernel is vulnerable to denial of service (DoS). The vulnerability exists as the fix for CVE-2011-2482 provided by RHSA-2011:1212 introduced a regression: on systems that do not have Security-Enhanced Linux (SELinux) in Enforcing mode, a socket lock race could occur between sctp_rcv() and sctp_accept(). A remote attacker could use this flaw to cause a denial of service. By default, SELinux runs in Enforcing mode on Red Hat Enterprise Linux 5.
