Linux Vulnerability – Important Update

N-able is aware of CVE-2026-98432, a recently disclosed vulnerability affecting certain versions of the Linux kernel. We have been assessing our products and environments for potential exposure and are actively applying applicable security updates as they become available from our operating system vendors.

Systems supporting Take Control and Mail Assure are currently being patched. For Cove, N-central, N-sight, Passportal, Adlumin, and other potentially impacted products, we are awaiting applicable operating system vendor patches and will deploy them once available.

For SpamExperts Local Cloud, N-able has released an updated kernel package. Customers must reboot their servers for the updated kernel to take effect. Until each server is restarted, it will continue to run the previous kernel. Customers should reboot servers one at a time and verify that each server has successfully rejoined the cluster before proceeding to the next.

At this time, we have no evidence that this vulnerability has been exploited in N-able-hosted environments. We will continue monitoring vendor guidance, evaluating our products and infrastructure, and taking appropriate action as additional updates become available.

Customers with questions or who need assistance completing the recommended actions should contact N-able Support.
