EPSS (Exploit Prediction Scoring System) estimates a 96.8% chance this CVE is exploited in the wild within the next 30 days — higher than 100% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Microsoft Internet Explorer contains an uninitialized memory corruption vulnerability that could allow for remote code execution. The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
