2021.2 IPU – Intel® Chipset Firmware Advisory

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.

CVSS Base Score: 7.3 High

CVSS Vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H

CVEID: CVE-2021-33068

Description: Null pointer dereference in subsystem for Intel® AMT before versions 15.0.35 may allow an authenticated user to potentially enable denial of service via network access.

CVSS Base Score: 5.0 Medium

CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L

CVEID: CVE-2021-0147

Description: Improper locking in the Power Management Controller (PMC) for some Intel Chipset firmware before versions pmc_fw_lbg_c1-21ww02a and pmc_fw_lbg_b0-21ww02a may allow a privileged user to potentially enable denial of service via local access.

CVSS Base Score: 4.4 Medium

CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H

Affected Products:

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.

Power Management Controller (PMC) for some Intel Chipset firmware versions before pmc_fw_lbg_c1-21ww02a and pmc_fw_lbg_b0-21ww02a.

Intel® AMT before version 15.0.35.

Recommendations:

Intel recommends that users of Intel® SPS, Intel® ADAS ME FW and Intel® CSME update to the latest version provided by the system manufacturer that addresses these issues.
