2021.2 IPU - Intel® Chipset Firmware Advisory

Intel ID:

INTEL-SA-00470

Advisory Category:

Firmware

Impact of vulnerability:

Escalation of Privilege, Denial of Service

Severity rating:

HIGH

Original release:

02/08/2022

Last revised:

02/08/2022

**Summary: **

Potential security vulnerabilities in some Intel® Chipset Firmware in Intel® Server Platform Services (SPS), Intel® Active Management Technology (AMT) and the Intel Power Management Controller (PMC) may allow escalation of privilege or denial of service. Intel is releasing firmware updates to mitigate these potential vulnerabilities.

Vulnerability Details:

CVEID: CVE-2021-0060

Description: Insufficient compartmentalization in HECI subsystem for the Intel® SPS before versions SPS_E5_04.01.04.516.0, SPS_E5_04.04.04.033.0, SPS_E5_04.04.03.281.0, SPS_E5_03.01.03.116.0, SPS_E3_05.01.04.309.0, SPS_02.04.00.101.0, SPS_SoC-A_05.00.03.114.0, SPS_SoC-X_04.00.04.326.0, SPS_SoC-X_03.00.03.117.0, IGN_E5_91.00.00.167.0, SPS_PHI_03.01.03.078.0 may allow an authenticated user to potentially enable escalation of privilege via physical access.
