Intel has addressed 73 security vulnerabilities as part of the June 2021 Patch Tuesday, including high severity ones impacting some versions of Intel's Security Library and the BIOS firmware for Intel processors.
Intel detailed the security flaws in the 29 security advisories published today on its Product Security Center.
"Today we released 29 security advisories addressing 73 vulnerabilities. 40 of those, or 55%, were found internally through our own proactive security research," Intel's Director of Communications Jerry Bryant said.
Intel provides a list of impacted products and recommendations for vulnerable products at the end of each advisory, together with contact details for security researchers who want to report security issues or vulnerabilities found in Intel branded tech.
June 2021 Intel Platform Update highlights
Of note, among the security updates released today, Intel addressed five high severity vulnerabilities impacting the Intel Virtualization Technology for Directed I/0 (VT-d) products, the BIOS firmware for some Intel processors, and the Intel Security Library.
The first of them (tracked as CVE-2021-24489) is caused by incomplete cleanup in some Intel VT-d products that could enable authenticated attackers to escalate privileges via local access.
Intel patched four more bugs (tracked as CVE-2020-12357, CVE-2020-8670, CVE-2020-8700, and CVE-2020-12359) caused by improper initialization, race condition, improper input validation, and insufficient control flow management in the CPU BIOS firmware allowing escalation of privilege via local or physical access.
The high severity bug patched in the Intel Security Library impacts versions before version 3.3, and it is caused by a key exchange without entity authentication enabling authenticated attackers to escalate privilege via network access.
Intel also patched 11 other high severity security vulnerabilities impacting Intel NUCs, Intel Driver and Support Assistant (DSA), Intel RealSense ID, Intel Field Programmable Gate Array (FPGA) Open Programmable Acceleration Engine (OPAE) driver for Linux, and Intel Thunderbolt controllers.
