We are currently carrying out a security intervention across our entire cloud infrastructure following the discovery of vulnerability CVE-2026-53359, also known as "Januscape".
This vulnerability affects the KVM component of the Linux kernel used by our hypervisors. Under certain conditions, it could allow a virtual machine to affect the host server and potentially escape its isolation boundary.
What actions have we taken?
A brief service interruption will be required on each node in order to apply the kernel patch and fully remediate this vulnerability.
We apologize in advance for any inconvenience this may cause and thank you for your understanding. Our team remains available should you have any questions.
