Q: What is the severity of CVE-2023-20578?

CVE-2023-20578 has a severity rating of critical due to its potential for arbitrary code execution by an attacker with ring0 privileges.

Q: How do I fix CVE-2023-20578?

To fix CVE-2023-20578, you should update your AMD Epyc firmware to a version that is not affected, specifically above genoapi_1.0.0.2 for designated models.

Q: Which devices are affected by CVE-2023-20578?

CVE-2023-20578 affects various AMD Epyc firmware versions prior to genoapi_1.0.0.2 on multiple Amd Epyc models.

Q: What is a TOCTOU vulnerability in the context of CVE-2023-20578?

A TOCTOU vulnerability, as seen in CVE-2023-20578, refers to the potential for an attacker to exploit a race condition between checking and using a resource.

Q: Is CVE-2023-20578 currently being exploited in the wild?

As of now, there are no confirmed reports of CVE-2023-20578 being actively exploited in the wild.

Published Aug 13, 2024

Updated

A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution.
