Threat Score
Microsoft's August 2024 Windows security update deployed an SBAT setting to block vulnerable UEFI shim bootloaders (addressing CVE-2022-2601) but in some dual-boot systems the change caused Linux systems with Secure Boot enabled to fail to boot, showing SBAT verification errors; Microsoft is investigating, provided an opt-out registry key to halt the update, and recommends disabling Secure Boot and reinstalling/updating Linux as the reliable recovery.
