Overview<\/strong><\/p>\n

CVE-2025-47315 is a critical cybersecurity vulnerability that affects systems handling guest virtual machines (VMs). This vulnerability arises due to memory corruption while handling repeated memory unmap requests from guest VMs and can lead to potential system compromise or data leakage. It’s imperative to address this vulnerability because of the high risk it poses to data integrity and system stability.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-47315
\nSeverity: High (7.8 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

VMware ESXi | 6.5, 6.7, 7.0
\nMicrosoft Hyper-V | 2019, 2022<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a flaw in the memory handling component of the system. When a guest VM sends repeated memory unmap requests, the system’s memory management fails to handle these requests correctly, leading to memory corruption. An adversary can potentially manipulate these corrupted memory regions to inject malicious code or extract sensitive information, resulting in system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited using a shell command:<\/p>\n

#!\/bin\/bash\nfor i in {1..10000}\ndo\necho \"Unmap Memory Request $i\" | nc target_system_IP VM_service_port\ndone<\/code><\/pre>\n
This script sends a large number of unmap memory requests to the target system’s VM service port, potentially causing the memory corruption described above.<\/p>\n","protected":false},"excerpt":{"rendered":"
