Canonical has issued a significant update for the Linux kernel, tackling a high-priority security flaw: CVE-2023-12345. Update your systems promptly.
Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 5.6 Long Life

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
* It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-8159, Important)
Red Hat would like to thank Mellanox for reporting this issue.
All kernel users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect.
