Update timeline

  1. identified May 07, 2026, 09:00 PM UTC

    We're currently deploying mitigations for the newly disclosed “Dirty Frag” (CVE-2026-43284) vulnerability. This issue affects the Linux kernel and may allow local privilege escalation to root access.

  2. resolved May 07, 2026, 10:15 PM UTC

    All mitigations have been applied, and the affected services are no longer vulnerable. A Linux kernel update is not yet available, as the embargo on this security issue was broken prematurely. We will deploy an updated kernel as soon as it becomes available. Any additional maintenance required for kernel updates will be announced by email.
