CVE-2026-4464 is an integer overflow vulnerability in the ANGLE graphics component of Google Chrome prior to version 146.0.7680.153. The flaw enables potential heap corruption when processing a crafted HTML page, as reported on March 20, 2026. It maps to CWE-190 (Integer Overflow or Wraparound) and CWE-472 (External Control of Critical State Data), with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Chromium security severity is rated as Medium.
A remote attacker can exploit this vulnerability by tricking a user into visiting a malicious website, requiring no privileges or special access. The low attack complexity and network vector make it accessible to attackers worldwide. Successful exploitation could grant high-impact confidentiality, integrity, and availability violations, potentially leading to heap corruption and arbitrary code execution within the browser's renderer process.
Google's stable channel update addresses the issue in Chrome 146.0.7680.153 and later versions, as announced in the Chrome Releases blog at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html. Further technical details are available in the Chromium issue tracker at https://issues.chromium.org/issues/487208468. Security practitioners should prioritize updating affected browsers and advise users to enable automatic updates.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
SI-10 directly requires validation of all inputs, eliminating the assumption that client-supplied parameters remain immutable.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require server-side validation of all inputs instead of trusting client-supplied immutable parameters.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure coding standards require server-side verification of client-supplied data, eliminating the root cause of external control of immutable parameters.
Security testing in development and acceptance will detect parameter tampering vulnerabilities before deployment.
Secure development lifecycle mandates input validation and integrity checks that directly prevent external tampering of assumed-immutable parameters.
Application security requirements explicitly call for validation of all inputs, including hidden fields, mitigating CWE-472.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Information access restriction can limit which parameters users may influence, providing a secondary layer of defense.
