CVE-2025-24984 Microsoft Windows: information leak
In plain words: The program reveals information it should keep private. Leaked secrets — tokens, passwords or memory contents — that help a bigger attack.
Confirmed exploited by CISA on · US federal patch deadline Apr 1, 2025
What to do
- Install Microsoft's security update for Windows. If no update exists, follow the vendor's workaround or stop using the product until one ships.
- Turn on automatic updates for the operating system and for Office, PDF and archive apps.
- Be careful with unexpected attachments — documents, .zip/.rar files and shortcuts are common bait.
- Use a normal (non-admin) account day to day and keep built-in protection like Microsoft Defender on.
Who is affected
Could reach you. This one is aimed at devices or apps of the kind people own.
What's at risk: Your files, saved passwords and accounts. Many of these let a program that is already running gain full administrator control.
