Last modified
CVE-2021-46747 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. Insufficient granularity of access control in ASP (AMD Secure Processor) may allow an attacker with an untrusted user space application to map sensitive SMN (System Management Network) apertures leading to a potential escalation of privileges.. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
