VMware ESXi 7.0 / 8.0 Sandbox Escape (CVE-2025-22225)

high Nessus Plugin ID 226453

Language:

Synopsis

The remote VMware ESXi host is affected by a sandbox escape vulnerability.

Description

The version of VMware ESXi installed on the remote host is 7.0 prior to 7.0 Update 3s, 8.0 Update 2 prior to 8.0 Update 2d, or 8.0 Update 3 prior to 8.0 Update 3d. It is, therefore, affected by a sandbox escape vulnerability:

 - VMware ESXi contains an arbitrary write vulnerability. A malicious actor with privileges within the VMX process may trigger an arbitrary kernel write leading to an escape of the sandbox. (CVE-2025-22225)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to VMware ESXi 7.0 Update 3s, 8.0 Update 2d, or 8.0 Update 3d or later.
