Detailsinfo

A vulnerability, which was classified as critical, has been found in AMD EPYC 9004 Processors, Ryzen Threadripper PRO 5000 WX-Series Processors, Ryzen 5000 Mobile Processors with Radeon Graphics, Ryzen Threadripper PRO 3000 WX-Series Processors, Ryzen Z1 Processors, Ryzen 9000 Desktop Processors, Ryzen 7000 Desktop Processors, Ryzen 3000 Mobile Processors with Radeon Graphics, Ryzen 5000 Desktop Processors with Radeon Graphics, Ryzen 3000 Desktop Processors, Ryzen 8000 Desktop Processors, Ryzen 7040 Mobile Processors with Radeon Graphics, Ryzen Threadripper 7000 processor, Ryzen Threadripper PRO 7000 WX-Series processors, Ryzen 8040 Mobile Processors with Radeon Graphics, Ryzen 4000 Mobile Processors with Radeon Graphics, Ryzen 6000 Processors with Radeon Graphics, Ryzen 8000 Desktop, Ryzen 7020 Processors with Radeon Graphics, Ryzen 7045 Mobile Processors with Radeon Graphics, Athlon 3000 Mobile Processors with Radeon Graphics, Ryzen 4000 Desktop Processors, Ryzen 5000 Desktop Processors, Ryzen Threadripper PRO 7000 WX-Series Processors, Ryzen Z2 Processors, Ryzen Z2 Processors Go, EPYC Embedded 9004 Processors, Ryzen Embedded R1000 Processors, Ryzen Embedded R2000 Processors, Ryzen Embedded 5000 Processors, Ryzen Embedded 7000 Processors, Ryzen Embedded V1000 Processors, Ryzen Embedded V2000 Processors, Ryzen Embedded V3000 Processors and Ryzen Embedded 8000 Processors. This issue affects an unknown code of the component SMM Handler. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. Using CWE to declare the problem leads to CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution.

The advisory is shared at amd.com. The identification of this vulnerability is CVE-2024-36355 since 05/23/2024. The exploitation is known to be difficult. An attack has to be approached locally. Additional levels of successful authentication are required for exploitation. Neither technical details nor an exploit are publicly available.

Upgrading eliminates this vulnerability.
