Описание
A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.

Меры по смягчению последствий
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:
echo "install sctp /bin/true" >> /etc/modprobe.d/disable-sctp.conf
The system will need to be restarted if the SCTP modules are loaded. In most circumstances, the SCTP 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 KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.
