CVE-2026-0482

Insufficient USB boot boundary check enabling buffer overflow and arbitrary code execution

Published Oct 5, 2026 CVSS 4.0 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
In AMD Versal™ Adaptive SoC devices, insufficient boundary checks in USB boot mode—when enabled through board modifications—could allow crafted images to trigger a buffer overflow and overwrite an active function pointer, which may result in arbitrary code execution during boot process. This condition could lead to potential impacts on confidentiality, integrity, and availability.
