An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing the input of an arbitrary message,. Rated medium severity (CVSS 5.6). No vendor patch available.
An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing arbitrary message input,. Rated low severity (CVSS 1.8). No vendor patch available.
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. Rated high severity (CVSS 7.1). No vendor patch available.
DDR5 memory modules in multiple AMD Ryzen processor families contain an insecure default PMIC (Power Management Integrated Circuit) interface configuration that allows local users with standard privileges to cause permanent denial of service or corrupt memory module integrity via unprotected firmware access. The vulnerability affects Ryzen 4000, 7000, 7020, 7030, 7035, 7040, 7045 series processors and Threadripper Pro 3000 WX-series, requiring local system access but no special privileges or user interaction. No public exploit code or active exploitation has been confirmed at time of analysis.
A compromised Trusted OS (TOS) driver could issue a malformed call that could potentially allow memory access outside the intended range resulting in loss of integrity. Rated low severity (CVSS 1.8). No vendor patch available.
Local privilege escalation in the AMD Platform Configuration Blob (APCB) SMM driver, shipped in AGESA firmware across nearly the entire modern AMD EPYC, Ryzen, Threadripper, and Instinct MI300 line, lets a Ring 0 attacker escalate into System Management Mode (SMM) and potentially run arbitrary code below the operating system. The flaw stems from the SMM driver improperly invoking UEFI boot services, and AMD-reported it with a CVSS 4.0 base of 7.1; there is no public exploit identified at time of analysis and EPSS is negligible at 0.01%. Because SMM code runs at a higher trust level than the OS kernel, successful exploitation can undermine firmware integrity and any SMM-based security guarantees.
