   We are currently rolling out and fixing CVE-2026-98432; so far, we have patched everything.

2. Scheduled 31 Oct 2026, 14:43 (CET)

   We are applying a security update for the Linux kernel (CVE-2026-98432) on all affected servers. Each affected server must be rebooted once for the update to take effect.

   The reboots are staggered, not performed on all servers at the same time. Based on experience, websites on each server will be unavailable for 1–2 minutes. Servers running an unaffected kernel generation will not be rebooted.

   No action is required from customers. After the reboot, the first page loads may be slightly slower while caches are rebuilt.
