CVE-2023-20579

Описание

Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability.

A vulnerability was found in AMD hardware due to improper access control in the AMD SPI protection feature. This issue may allow a local user with Ring0 (kernel mode) privileged access to bypass protections, potentially resulting in loss of integrity and availability.

Отчет

The PSP and AEGIS vulnerabilities necessitate a BIOS update, as they are not inherent to the CPU and cannot be addressed through CPU microcode updates. This requires a UEFI firmware update from the device vendor, distinct from updates in the linux-firmware package. Therefore, linux-firmware on Red Hat Enterprise Linux is marked as not affected.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
