# Use after free in CSS in Google Chrome prior to 145.0.7632.75 allowed a remote attacker to execute arbitrary code…

A use-after-free bug in Chromium's CSS handling lets a remote attacker corrupt heap memory by getting a victim to load a crafted HTML page. Attackers can use this kind of memory corruption to run code inside the browser, and CISA reports it is already being 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 < 145.0.7632.75 fixed 145.0.7632.75
- vendor:google chrome affected < 145.0.7632.76 fixed 145.0.7632.76

## How to check

Check the installed browser version in chrome://version (or edge://version, opera://version) and compare it against the fixed release named by the vendor.

## Fix

Update Google Chrome, Microsoft Edge, Opera and other Chromium-based browsers to the latest stable release that includes the vendor's fix for this CVE.
Follow CISA's guidance: apply vendor mitigations, or stop using the product if no mitigation is available.

## From the sources

Google Chromium CSS contains a use-after-free vulnerability that could allow a remote attacker to potentially exploit heap corruption 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.
