CVE-2025-48807 is a vulnerability in Windows Hyper-V that allows local code execution via VSP channels. The issue stems from improper restriction of a Hyper-V communication channel to its intended endpoints, enabling an authorized attacker to execute code locally on an affected host. This host-side weakness in Hyper-V integration paths can be abused through malformed or misdirected requests processed in privileged host contexts, leading to memory or logic conditions that permit code execution with elevated privileges.
