CVE-2025-24984: Microsoft Windows

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

Yes, if you run Microsoft Windows. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-03-11, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-04-01; treat that as the outer limit, not the target.
EPSS 2.0%, percentile 81: FIRST’s model estimates a 2.0% chance of exploitation activity in the next 30 days, higher than 81% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
Needs physical access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
