Intel has fixed 73 security vulnerabilities as part of the June 2021 Patch Tuesday, including serious vulnerabilities affecting several versions of Intel’s Security Library and the BIOS firmware for Intel processors.
In its advisory, Intel includes a list of affected products and recommendations for vulnerable products, as well as contact details for security researchers wishing to report security problems or vulnerabilities in Intel products.
Among the security updates released recently, Intel focused on five serious vulnerabilities affecting 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 purges in some Intel VT-d products that could allow authenticated attackers to elevate privileges over local access.
Intel has patched four other 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 in the CPU BIOS firmware, allowing for privilege escalation via local or physical access.
Intel has also fixed 11 other vulnerabilities affecting Intel NUCs, Intel Driver and Support Assistant, Intel RealSense ID, Intel Field Programmable Gate Array, Open Programmable Acceleration Engine driver for Linux and Intel Thunderbolt controllers.
