EPSS Score88.6%

EPSS (Exploit Prediction Scoring System) estimates a 88.6% 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.

The Universal 3D (U3D) component in Adobe Reader and Acrobat contains a memory corruption vulnerability which could allow remote attackers to execute code or cause denial-of-service (DoS).
