A vulnerability was found in the Linux kernel. This flaw allows an unprivileged local user to panic the system, resulting in a denial of service by calling setsockopt(2) with specially crafted arguments. The highest threat from this vulnerability is to system availability.
As the SCTP module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:
The system will need to be restarted if the SCTP modules are loaded. In most circumstances, the CIFS kernel modules will be unable to be unloaded while any network interfaces are active and the protocol is in use.
If the system requires this module to work correctly, this mitigation may not be suitable.
If you need further assistance, see the KCS article <https://access.redhat.com/solutions/41278> or contact Red Hat Global Support Services.
