Summary

CVE-2025-0436 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 in the top 33.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and SC-39 (Process Isolation).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Requires timely identification, reporting, and remediation of flaws, directly addressing the integer overflow in Skia by applying Google's patch in Chrome 132.0.6834.83.

prevent

Process isolation through browser sandboxing confines potential heap corruption in the Skia renderer process, limiting attacker impact to the sandboxed environment.

prevent

Memory protection mechanisms like ASLR and DEP mitigate heap corruption exploits by randomizing memory layout and preventing execution of corrupted heap data.

MITRE ATT&CK Enterprise TechniquesAI

T1189 Drive-by Compromise Initial Access
Adversaries may gain access to a system through a user visiting a website over the normal course of browsing.
T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
T1204.001 Malicious Link Execution
An adversary may rely upon a user clicking a malicious link in order to gain execution.
Why these techniques?

Integer overflow in browser rendering library enables drive-by compromise via malicious HTML (T1189), client-side exploitation for code execution (T1203), and user-triggered execution via crafted link (T1204.001).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

Integer overflow in Skia in Google Chrome prior to 132.0.6834.83 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Deeper analysisAI

CVE-2025-0436 is an integer overflow vulnerability in the Skia graphics library used by Google Chrome prior to version 132.0.6834.83. The flaw enables potential heap corruption when rendering a crafted HTML page, as classified under CWE-472. Chromium rates its security severity as High, 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).

A remote attacker can exploit this vulnerability by luring a user to visit a malicious website containing the crafted HTML page, requiring user interaction such as clicking a link but no special privileges. Successful exploitation could allow the attacker to achieve high-impact corruption of the heap, potentially leading to arbitrary code execution and full compromise of the browser's confidentiality, integrity, and availability.

Google's stable channel update for desktop, announced via the Chrome Releases blog, patches this issue in version 132.0.6834.83 and later. Additional technical details are documented in the associated Chromium issue tracker. Security practitioners should prioritize updating affected Chrome installations to mitigate the risk.
