This week, Microsoft released its Patch Tuesday security updates for Windows 11 and Windows 10, among others. The updates were supposed to kick off the third phase of Kerberos hardening, though that has now been pushed back a few months. Perhaps the update isn’t ready for rollout yet because Microsoft’s internal testing revealed some deployment issues.
However, it looks like Redmond has now republished a smaller update alongside the monthly Patch Tuesday. on the Microsoft Update Catalog website, the KB5012170 update is available for download as a cumulative update for Windows 11 and Windows 10. The release date of the KB corresponds to Patch Tuesday.
In August, Microsoft released a security fix for a critical Secure Boot DBX GRUB vulnerability (KB5012170). The update was found to cause problems as it was failing to install with error code 0x800f0922, and as a workaround, Microsoft suggested updating the UEFI. And a week later, Microsoft also acknowledged another issue related to the KB5012170 update. This time, users reported that after installing the update, their systems were forced into BitLocker recovery mode, prompting the Redmond firm to provide steps to fix the bug. Microsoft’s Health Dashboard Still lists these bugs as “investigated” and “confirmed” which means it’s possible the tech dev has re-pushed the buggy update.
