AMD Secure Processor (ASP) PCI Driver Vulnerabilities

Buffer overflow in the AMD Secure Processor (ASP) PCI driver affects dozens of AMD Ryzen, EPYC, and Threadripper processor families across desktop, mobile, and embedded variants. Local attackers with user-level privileges can trigger improper input validation in the driver to cause a crash or denial of service, with potential for integrity impact. The vulnerability requires local access and authenticated user privileges; no active exploitation in the wild has been confirmed, and vendor-released patches are available.

Use-After-Free vulnerability in the AMD Secure Processor (ASP) PCI driver affects multiple Ryzen, Threadripper, EPYC, and Athlon processor families due to improper input validation. A local attacker with user-level privileges can trigger the UAF condition, resulting in denial of service via platform crash or potential loss of platform integrity. Vendor-released patch: AMD Ryzen Chipset Driver 7.02.13.148 (or equivalent Catalyst driver versions for embedded SKUs). No public exploit identified at time of analysis.
