The protections for this vulnerability are not included in the following May 2025 monthly rollup or security-only updates released on May 13, 2025:
- Windows Server 2008 R2: KB5058454 (Security-only update)

- Windows Server 2008: KB5058429 (Security-only update)
- Windows Server 2008: KB5058449 (Monthly Rollup)
Instead, customers running these versions of Windows Server need to install the following Out-of-Band (OOB) updates, released also on May 13, 2025, as applicable:
- Windows Server 2008 R2: KB5061195 (Security-only update)
- Windows Server 2008 R2: KB5061196 (Monthly Rollup)
- Windows Server 2008: KB5061197 (Security-only update)
- Windows Server 2008: KB5061198 (Monthly Rollup)
Note These OOB updates are cumulative, so if you haven't already installed the May 2025 monthly rollup or security-only updates, you can install the applicable OOB update directly. If you have already installed the May 2025 monthly rollup or security-only updates, you need to also install the OOB updates to be protected from this vulnerability.
