Component Updates¶

CVE-2026-98432 Mitigations¶

During this week we started the rollout of mitigations for the IPv4 TCP vulnerability in the Linux kernel. The patch is automatically applied during the regular maintenance run, no action is required from customers.

If you want to apply it off-cycle, you can always trigger maintenance run in your Ketesa admin panel -> Server Actions.

How to verify the patch is already applied to your server: check existence of /etc/systemd/system/matrix-cve-2026-98432.service file (if the file exists, then the nftables mitigations are already applied)

Once distributives start publishing fixed kernels, they will be installed automatically during the regular maintenance process.
