Summary
CVE-2026-3536 is a high-severity External Control of Assumed-Immutable Web Parameter (CWE-472) vulnerability in Google Chrome. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Drive-by Compromise (T1189); ranked at the 36.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and RA-5 (Vulnerability Monitoring and Scanning).
Deeper analysis
CVE-2026-3536 is an integer overflow vulnerability (CWE-190) in the ANGLE graphics component of Google Chrome prior to version 145.0.7632.159. The flaw enables a remote attacker to potentially perform out-of-bounds memory access via a crafted HTML page, as reported on March 4, 2026. Chromium rates it as Critical severity 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), also linked to CWE-472.
A remote attacker without privileges can exploit this by luring users to visit a malicious site hosting the crafted HTML page, requiring user interaction such as clicking a link. Low attack complexity enables broad potential reach. Exploitation could grant high-impact confidentiality, integrity, and availability compromises, including out-of-bounds memory access that may lead to code execution or system crashes.
Mitigation is available via the Google Chrome stable channel update to version 145.0.7632.159 or later, as announced in the Chrome Releases blog at chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop.html. Additional details on the fix are documented in the Chromium issue tracker at issues.chromium.org/issues/485622239. Security practitioners should prioritize updating affected Chrome installations.
