Intel and AMD have disclosed more than 200 security vulnerabilities affecting processors, graphics products, firmware and associated software. Their latest advisories identify critical weaknesses in Intel technology and numerous AMD flaws, with fixes available for many, but not all, affected products.
How Many Flaws Did Intel Report?
Intel issued 24 security advisories covering just over 100 vulnerabilities, including three rated critical and 20 classified as high severity.
The largest advisory covers 30 flaws in the TDX Migration Trust Domain (MigTD) reference software. Three are critical authentication-related weaknesses that could enable attackers to increase their privileges. One, identified as CVE-2026-61887, could also permit remote code execution.
The findings put particular attention on systems that rely on this software for secure operations.
Which Other Intel Products Are Affected?
Intel addressed high-severity privilege escalation issues in Slim Bootloader, firmware for D50DNP and M50FCP server boards, and its VTune Profiler software.

Separate fixes cover denial-of-service weaknesses affecting PROSet/Wireless WiFi and Bluetooth products, as well as Performance Counter Monitor software. Other medium-severity issues were resolved in graphics drivers, NPU drivers, Neural Compressor, Hyperscan, oneDNN, oneAPI CLI Tool and additional components.
What About Unsupported Software?
Three medium-severity privilege escalation vulnerabilities affect Intel’s discontinued BigDL software.
Intel will not issue patches for these flaws because the product is no longer supported. The company advises users to uninstall BigDL or discontinue its use as soon as possible. This leaves affected organisations needing to remove the software rather than wait for security updates.
What Did AMD Disclose?
AMD published 29 security bulletins and two security briefs covering approximately 100 distinct vulnerabilities. None received a critical severity rating, although several were classified as high severity. Graphics products account for the largest group. One bulletin identifies 44 issues in Radeon and Instinct products, including ten high-severity vulnerabilities.
AMD also identified firmware security weaknesses affecting protected system functions and administrative controls. Several findings involve third-party technology and software used alongside AMD’s own hardware products.
Which AMD Flaws Are Serious?
One high-severity UEFI vulnerability could allow an attacker with elevated access to execute arbitrary code in System Management Mode.
Another could bypass Secure Debug Unlock protections. Additional flaws involve an IOMMU weakness capable of causing denial of service from a compromised guest virtual machine and a TianoCore EDK II issue that could corrupt protected memory.
In AMD Management Console, a missing authentication weakness could expose saved credentials. Vivado Lab Solutions also has a privilege escalation flaw. More than two dozen medium-severity issues affect Secure Encrypted Virtualization.
Are All Patches Available?
Security fixes and mitigations are available for many affected products, but some AMD updates remain under development and may not arrive until 2027.
AMD also published findings related to transient scheduler attacks on Zen 5 processors, including concerns about mitigation differences across processor generations. The advisories underline the need for organisations to identify affected hardware and software, review vendor guidance and apply available updates promptly.
