Chrome Skia Sandbox Escape via HTML Page

CVE advisorySeverity: CRITICAL (CVSS 9.6)

CVE-2026-14419

This vulnerability affects the Skia graphics library within a web browser, requiring the target to visit a crafted HTML page. As a client-side component, it is not an internet-facing service, listener, or gateway; exposure relies on user interaction with untrusted content rather than public network reachability of a server or appliance.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability in the Skia graphics component of Google Chrome could allow an attacker to escape the browser's sandbox by luring a user to a malicious webpage. This could potentially lead to broader system compromise if an attacker can leverage this access.

Attack Path

How an attacker could exploit the issue

An attacker can initiate an attack by directing a user to a malicious webpage. This webpage contains specially crafted content designed to trigger a use-after-free vulnerability within the Skia graphics component of the browser. If successful, this vulnerability could allow the attacker to break out of the browser's security sandbox.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability resides in the Skia graphics library within Google Chrome and requires user interaction with a malicious HTML page to trigger a potential sandbox escape. Initial triage should focus on identifying Chrome deployments, confirming exposure through user access to untrusted web content, and assessing business criticality. Coordination with browser administrators or endpoint security teams will be necessary to plan and execute remediation.

Frequently asked questions

What is the Skia component in Google Chrome?

Skia is an open-source 2D graphics library that provides the rendering engine for Google Chrome. It is responsible for drawing the text, shapes, and images you see on webpages. Because it handles complex visual data from various sources, it must be highly performant and secure to prevent malicious content from manipulating the underlying system memory.

What does CVE-2026-14419 mean by use-after-free?

A use-after-free is a memory corruption weakness, classified as CWE-416. It occurs when a program continues to use a pointer to a memory address after that memory has been cleared or reclaimed. An attacker can manipulate this state to insert their own data into that memory location, potentially taking control of the application's execution flow.

How is the Skia use-after-free triggered?

This vulnerability is triggered when a user visits a specifically crafted HTML page that exploits the graphics rendering process. It does not trigger through background network traffic or static file viewing alone; it requires the browser to actively process the malicious code within the page to cause the memory error.

Is my system at high risk from this Chrome flaw?

Halo Surface Signal notes that this is a client-side issue, not a public-facing service or gateway vulnerability. Your risk depends on users navigating to untrusted websites. If your environment primarily limits browsing to known, secure locations, the practical likelihood of encountering a malicious page designed to exploit this specific memory error is lower.

How do I address CVE-2026-14419?

The primary response is to ensure all browser installations are updated to version 150.0.7871.46 or later, which contains the fix for this graphics component flaw. Since this requires user interaction, prioritize updating endpoints where users frequently access diverse or untrusted web content. Coordination with your desktop or browser management teams is the standard path for deploying these updates.
