Microsoft released KB5084597 as an out-of-band hotpatch for Windows 11 Enterprise devices, closing RRAS remote-code-execution flaws that affect hotpatch-managed systems. The update covers Windows 11 25H2, 24H2, and Windows 11 Enterprise LTSC 2024. Microsoft says the fix is cumulative and includes the March 2026 security-update changes. The release matters because eligible devices can get the remediation without a restart, which is useful for mission-critical remote management environments.
