CVE-2023-20533 has a high severity due to its potential to enable denial-of-service conditions through unauthorized access to invalid DRAM addresses.
To mitigate CVE-2023-20533, users should update the firmware of affected AMD EPYC processors to the latest version provided by AMD.
CVE-2023-20533 affects various AMD EPYC processor firmware versions prior to romepi_1.0.0.d and milanpi_1.0.0.5.
The potential impacts of CVE-2023-20533 include unauthorized memory access leading to data corruption and denial of service.
CVE-2023-20533 requires local access to the system for exploitation, making it less of a remote vulnerability.
