Questions about CVE-2025-22226
What does this mean?
An out-of-bounds read in the HGFS component can leak memory from the vmx process. The issue requires an attacker with administrative privileges on a virtual machine.Source: support.broadcom.com
Am I affected, and how do I check?
The listed ranges cover ESXi 7.0 and 8.0, VMware Workstation 17.x, and VMware Fusion 13.x, before the fixed builds named in the advisory. Check your product version against those ranges. Cloud Foundation, Telco Cloud Platform, and Telco Cloud Infrastructure are named without version ranges, so check the vendor's response matrix for them.Source: support.broadcom.com
What should I do about it?
Upgrade ESXi 8.0 to ESXi80U3d-24585383 or ESXi80U2d-24585300, ESXi 7.0 to ESXi70U3s-24585291, Workstation to 17.6.3, and Fusion to 13.6.3.Source: support.broadcom.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2025-03-04, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
