Fixing CVE-2026-53359 (Januscape) and CVE-2026-46113 on Talos Linux

Update on CVE-2026-53359 (“Januscape”): the proper fix is here.

Our earlier mitigation was a hotfix — a temporary, forced measure. The proper fix is now available, so the hotfix is no longer needed.

TL;DR: Disabling nested virtualization is no longer needed. It was a hotfix, and for some setups it wasn’t even possible. The real fix is a kernel bump. If you already applied the hotfix, roll it back and upgrade instead.
