Use after free in Extensions in Google Chrome prior to 146.0.7680.153 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption via a crafted Chrome Extension. (Chromium security severity: High)
AnalysisAI
Heap memory corruption in Google Chrome prior to version 146.0.7680.153 can be triggered through malicious browser extensions, affecting Chrome users on Google, Ubuntu, and Debian systems. An attacker must convince a user to install a compromised extension to exploit this use-after-free vulnerability and potentially achieve code execution. A patch is available.
Technical ContextAI
This vulnerability is rooted in CWE-416 (Use After Free), a memory safety defect where a program continues to access heap-allocated memory after it has been deallocated. The affected subsystem is Google Chrome's Extension API layer, which provides privileged access to browser internals for installed extensions. When an extension interacts with Chrome's native code through the Extension framework, improper lifetime management of heap objects can result in a freed pointer being dereferenced. This is particularly dangerous in the context of extensions because they operate with elevated privileges relative to web content. The vulnerability affects Chrome versions distributed through the Debian package ecosystem (9 releases tracked) and requires interaction with the crafted extension's malicious code path to trigger the heap corruption.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later using the official stable channel distribution available at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html. For enterprise deployments, push this update through your standard patch management process with high priority. Until patching is complete, implement extension policy controls via Chrome's ExtensionSettings group policy (or equivalent) to prevent installation of untrusted extensions—use a whitelist of approved extensions rather than allowing arbitrary installation. Consider restricting the set of users who can install extensions to trusted administrators only. For Debian-based systems, update the chromium or chromium-browser package to the patched version through apt. Verify successful patching by checking chrome://version in the browser to confirm the version number is 146.0.7680.153 or higher.
