# Insufficient validation of untrusted input in ANGLE and GPU in Google Chrome prior to 138.0.7204.157 allowed a…

Google Chromium's ANGLE and GPU components improperly validate input, so a crafted HTML page can make the browser's GPU process escape its sandbox. CISA lists it as actively exploited in the wild.

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

## Affected

- vendor:Google Chromium affected ? fixed ?
- vendor:google chrome affected < 138.0.7204.157 fixed 138.0.7204.157
- vendor:debian linux affected = 11.0 fixed ?
- vendor:apple safari affected < 18.6 fixed 18.6
- vendor:apple ipados affected < 18.6 fixed 18.6
- vendor:apple iphone os affected < 18.6 fixed 18.6
- vendor:apple macos affected < 15.6 fixed 15.6
- vendor:apple visionos affected < 2.6 fixed 2.6
- vendor:apple watchos affected < 11.6 fixed 11.6
- vendor:wpewebkit wpe webkit affected < 2.48.5 fixed 2.48.5
- vendor:webkitgtk affected < 2.48.5 fixed 2.48.5

## How to check

Check the installed Chrome, Edge or Opera version against the vendor's fixed release (version not given in the sources).

## Fix

Update Google Chrome, Microsoft Edge, Opera or other Chromium-based browsers to the patched release from the vendor. Follow CISA's required action: apply vendor mitigations or stop using the product if no mitigation exists.

## From the sources

Google Chromium contains an improper input validation vulnerability in ANGLE and GPU. This vulnerability could allow a remote attacker to potentially perform a sandbox escape via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.

CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
