Chipmaker Patch Tuesday: Intel and AMD Patch 70 Vulnerabilities
Intel and AMD have released over two dozen advisories on May 2026 Patch Tuesday, addressing 70 vulnerabilities across their product portfolios.
Intel published 13 advisories describing 24 security defects, including one critical and eight high-severity flaws.
The critical bug, tracked as CVE-2026-20794 (CVSS score of 9.3), is described as a buffer overflow issue in the Data Center Graphics Driver for VMware ESXi software that could be exploited for privilege escalation and potentially for code execution.
Intel’s update for the product also resolves two high-severity out-of-bounds write and read weaknesses that could lead to denial-of-service (DoS) conditions and potentially to data corruption or disclosure.
The chip maker also addressed high-severity vulnerabilities in Vision software, Endpoint Management Assistant (EMA), UEFI firmware for the Slim Bootloader, and QuickAssist Technology (QAT) software drivers for Windows.
Successful exploitation of the flaws could lead to DoS conditions and privilege escalation, and potentially arbitrary code execution.
