CVE-2026-18349

SAMA5D44 Fault Injection Vulnerability

Published Aug 24, 2026 CVSS 4.0 · 7.3 High EPSS < 1% KEV · Not listed
Description
Improper protection against voltage and clock glitches vulnerability in Microchip SAMA5D4 allows Hardware Fault Injection.

This issue affects SAMA5D4.

Remediation

Vendor Solution

Because this attack requires direct physical access to the device’s core power supply, the most effective protection is to prevent such access. Customers deploying the SAMA5D4 in security-sensitive applications should review the physical-security assumptions of their deployment and consider measures that make the core supply rail physically inaccessible.  This includes avoiding exposed test points or headers on that rail and employing mechanical protections such as potting, conformal coating, shielding, or tamper-resistant enclosures to prevent attachment of fault-injection equipment.
