Insecure installation directory permissions in AMD chipset driver allow local authenticated attackers to achieve SYSTEM-level privilege escalation and execute arbitrary code. The vulnerability affects nearly all AMD Ryzen, Threadripper, EPYC, and Athlon processors across desktop, mobile, embedded, and server product lines. AMD has released patched chipset driver versions 8.01.20.513 (consumer/workstation) and 8.03.14.329/8.03.16.641 (server). No active exploitation confirmed at time of analysis, but the local vector and low attack complexity make this exploitable by any authenticated Windows user, including standard users without admin rights.
Improper Input Validation in the AMD RAID driver could allow an attacker to point to an arbitrary memory location potentially resulting in privilege escalation and arbitrary code execution. Rated high severity (CVSS 8.6), this vulnerability is low attack complexity. No vendor patch available.
System Management Mode (SMM) handler in AMD Ryzen mobile, desktop, embedded, Threadripper, and EPYC processors allows privileged local attackers to execute arbitrary code in SMM by triggering a callout to attacker-controlled code in untrusted non-SMM memory. The vulnerability requires high complexity conditions, active user interaction, physical proximity or direct system access, and high privilege level; successful exploitation compromises system confidentiality, integrity, and availability. No public exploit identified at time of analysis.
