EPSS Score1.6%

EPSS (Exploit Prediction Scoring System) estimates a 1.6% chance this CVE is exploited in the wild within the next 30 days — higher than 76% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. Successful exploitation allows an attacker with administrative privileges to a virtual machine to leak memory from the vmx process.

Required Action
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
