Amd Ryzen 6000 Series Processors With Radeon Graphics
Monthly
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.
Improper input validation in the System Management Mode (SMM) communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity. 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.
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.
