# Chrome: uninitialized Skia memory lets a compromised renderer read outside the sandbox

Link for people: https://infrastack.ai/live/CVE-2026-126853 (this .md is for agents)

Google Chrome's Skia graphics library uses a resource it never initialized. A remote attacker who has already compromised the renderer process can read memory outside the sandbox by serving a crafted HTML page.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Chrome version in the browser's About page or with `chrome://version`; versions before `157.0.8103.78` are exposed.
- On managed fleets, query the installed Chrome version through the device management console.

## Fix

- Google Chrome: update to `157.0.8103.78` or later.

## Timeline

- 2026-11-11T23:29:36+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-126853

## From the sources

Uninitialized resource in Skia in Google Chrome prior to 157.0.8103.78 allowed a remote attacker who had compromised the renderer process to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: High)
