Intel this week announced patches for dozens of vulnerabilities across its product portfolio, including critical- and high-severity issues.
The most severe of these flaws is CVE-2021-39296 (CVSS score of 10), which impacts the Integrated Baseboard Management Controller (BMC) and OpenBMC firmware of several Intel platforms.
The bug was identified in 2021 in the netipmid (IPMI lan+) interface and could allow an attacker to obtain root access to the BMC, bypassing authentication using crafted IPMI messages.
Four other vulnerabilities were addressed in BMC and OpenBMC firmware, including a high-severity out-of-bounds read issue that could lead to denial-of-service (DoS).
Intel has addressed these bugs with the release of Integrated BMC firmware versions 2.86, 2.09 and 2.78, and OpenBMC firmware versions 0.72, wht-1.01-61, and egs-0.91-179.
Patches were also released for a high-severity privilege escalation defect in Xeon processors with SGX (CVE-2022-33196). Both BIOS and microcode updates that address this issue are now available.
Intel also warned of a high-severity escalation of privilege issue (CVE-2022-21216) impacting Atom and Xeon processors, and released microcode updates for Xeon to address CVE-2022-33972, an incorrect calculation bug that could lead to information disclosure.
This week, the chip maker announced updates that resolve high-severity privilege escalation defects in the BIOS firmware and Trusted Execution Technology (TXT) Secure Initialization (SINIT) Authenticated Code Modules (ACM) of some processors.
Updates were also released to resolve high-severity flaws in Driver Support Assistant (DSA) software, and high- and medium-severity vulnerabilities in Battery Life Diagnostic Tool, oneAPI Toolkits, System Usage Report (SUR), Server Platform Services (SPS) firmware, and Quartus Prime Pro and Standard edition software.
Various medium-severity vulnerabilities were resolved in the FPGA SDK for OpenCL Quartus Prime Pro software, Integrated Sensor Solution, Media Software Development Kit (SDK), Trace Analyzer and Collector software, and Xe MAX drivers for Windows.
Intel recommends that users update to the latest available firmware and software versions as soon as possible. Additional information on the resolved vulnerabilities can be found at Intel’s security center.
