The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The victim must open a crafted HTML page in Google Chrome versions prior to 146.0.7680.153. Remote attacker sends malicious webpage; no authentication or special configuration required. User interaction (opening the page) is mandatory.

Impact

While the Chromium security team assigned High severity classification, the real-world risk requires nuanced assessment across multiple signals. The vulnerability is network-accessible (CVSS Attack Vector: Network) with low attack complexity, requiring only a user visit to a malicious webpage—no user-assisted exploitation needed beyond clicking a link. The absence of CVSS numerical score and EPSS probability data limits quantitative risk modeling, but the information disclosure nature (memory read, not code execution) represents a lower impact tier than remote code execution vulnerabilities. A patch is available and stable version 146.0.7680.153 has been released, reducing active exploitation window. The vulnerability does not appear on known exploit databases or KEV catalogs at this time, suggesting limited current weaponization. However, memory disclosure vulnerabilities are often chained with other flaws for sandbox escape, making this a genuine secondary risk component in sophisticated attacks. Priority should be driven by organizational Chrome deployment scale rather than standalone CVSS rating.

Exploit ScenarioDerived

An attacker creates a malicious website containing crafted SVG or WebGL content designed to trigger the out-of-bounds read in Skia's rendering pipeline. When a user visits the site, Chrome automatically renders the malicious graphics, causing the Skia library to read memory outside buffer bounds. The attacker captures the leaked memory contents, which may contain credentials, encryption keys, or data from other browser tabs. This information disclosure could enable follow-up attacks such as session hijacking or sandbox escape if combined with additional vulnerabilities. No public proof-of-concept is currently documented, but the attack requires no interaction beyond visiting the webpage.

AnalysisAIv1 – Mar 20, 2026

Memory disclosure in Google Chrome's Skia rendering engine prior to version 146.0.7680.153 enables unauthenticated attackers to read out-of-bounds memory contents by tricking users into visiting malicious web pages. Affected users across Chrome, Ubuntu, and Debian distributions face potential information leakage including sensitive data from process memory. A patch is available for immediate deployment.

Earlier versions of this analysis (1)
v1 Mar 20, 2026 - 08:37 CVSS 8.8

An out-of-bounds read vulnerability exists in Google Chrome's Skia rendering engine, affecting versions prior to 146.0.7680.153, allowing remote attackers to read memory beyond allocated buffer boundaries through specially crafted HTML pages. The vulnerability enables information disclosure, potentially exposing sensitive data from the browser's memory space. This is a network-based attack requiring only user interaction (visiting a malicious webpage) with no authentication or elevated privileges needed, classified by Chromium as High severity.

RemediationAI

Immediately upgrade Google Chrome to version 146.0.7680.153 or later. For users on Debian systems, update chromium or chromium-browser packages to the patched version through apt-get update && apt-get upgrade chromium-browser. Organizations managing enterprise Chrome deployments should use the Chrome Enterprise update management console to force deployment of version 146.0.7680.153 or later. Until patching is complete across all systems, enforce Content Security Policy (CSP) headers with script-src and style-src restrictions on internal web applications to reduce attack surface from malicious HTML injection. Additionally, implement browser isolation or sandboxing solutions for high-risk user populations, and restrict access to untrusted websites through URL filtering or proxy-based content inspection.

Technical ContextAI · show details

The vulnerability resides in Skia, Google's open-source 2D graphics library used as the core rendering engine in Chromium-based browsers. The root cause is classified as CWE-125 (Out-of-bounds Read), a memory safety issue where the Skia library fails to properly validate buffer boundaries during graphics processing operations. When parsing or rendering crafted HTML content containing malicious SVG, canvas, or WebGL elements, the renderer reads memory locations beyond the intended buffer, potentially exposing heap or stack memory. The affected product is Google Chrome prior to version 146.0.7680.153, with additional tracking across Debian systems where 9 releases are affected as downstream consumers of Chromium.

DescriptionCVE.org

Out of bounds read in Skia in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: High)

Executive ViewAI

Why It Matters

Organizations using Skia in Google Chrome face significant risk from CVE-2026-4460, a out-of-bounds read vulnerability rated CVSS 8.8. Successful exploitation could significantly impact the confidentiality, integrity, or availability of affected systems. A patch is available and should be applied as part of regular vulnerability management.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
