Multiple vulnerabilities in Intel Chipset Firmware

1) Improper isolation or compartmentalization

EUVDB-ID: #VU60450

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-0060

CWE-ID: CWE-653 - Improper isolation or compartmentalization

Exploit availability: No

Description

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists due to insufficient compartmentalization in HECI subsystem for the Intel(R) SPS. An attacker with physical access to the system can execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's website.

2) NULL pointer dereference

EUVDB-ID: #VU60451

Risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-33068

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in subsystem for Intel(R) AMT. A remote user can pass specially crafted data to the system and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

AMT SDK: before 15.0.35
