Use after free in Base in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Heap corruption in Google Chrome versions before 146.0.7680.153 results from a use-after-free vulnerability in the Base component, enabling remote attackers to execute arbitrary code through malicious HTML pages. The attack requires user interaction but no authentication, affecting Chrome on multiple platforms including Linux distributions. A patch is available to remediate this critical-severity vulnerability.
Technical ContextAI
The vulnerability is rooted in CWE-416 (Use After Free), a memory safety flaw where the Base component in Chrome attempts to access heap memory that has been freed. The Chromium browser engine, which powers Google Chrome and is embedded in numerous other applications, manages memory through allocation and deallocation routines; when the Base library fails to properly track object lifecycles, dangling pointers can be dereferenced, leading to heap corruption. This affects Chrome on Windows, macOS, Linux, Android, and iOS platforms, with the vulnerability specifically introduced or unpatched in versions below 146.0.7680.153. The attack surface is the HTML parsing and rendering pipeline, where a malicious webpage can trigger the vulnerable code path through crafted DOM structures or event sequences.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later by navigating to Menu > Help > About Google Chrome, which will automatically check for and install available updates. For enterprise environments, deploy the patched version through your MDM/device management solution and verify rollout across all endpoints. Until patching is complete, network-level mitigations include restricting access to untrusted websites via proxy filtering, enabling Chrome's enhanced safe browsing mode, and considering disabling JavaScript in high-risk browser profiles if operationally feasible. For Debian systems, update the chromium or google-chrome packages through your package manager (apt update && apt upgrade) once the fixed version is released to your distribution channel. Verify patch installation by checking Chrome's version in Settings > About; Chrome should not proceed to the next major version (147+) without confirming 146.0.7680.153 or later is installed.
