Use after free in Network 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: High)
AnalysisAI
Heap memory corruption in Google Chrome versions prior to 146.0.7680.153 can be triggered through a use-after-free vulnerability in the Network component when a user visits a malicious HTML page. An unauthenticated remote attacker can exploit this to achieve arbitrary code execution with high integrity and confidentiality impact. A patch is available for Chrome, Ubuntu, and Debian users.
Technical ContextAI
This vulnerability is rooted in CWE-416 (Use After Free), a memory safety defect where the application attempts to access heap memory after it has been deallocated. The flaw is located in Google Chrome's Network processing subsystem, which handles HTTP/HTTPS requests and responses. Use-after-free vulnerabilities in network stacks are particularly dangerous because they can corrupt critical heap structures managing connection state and buffers. The affected component processes untrusted input from crafted HTML pages, making it remotely exploitable without user interaction beyond visiting a malicious website. The vulnerability affects multiple Debian packages tracking Chrome releases across 9 different package versions.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later by navigating to Settings > About > Google Chrome, which will trigger automatic download and installation of the patched version. For Debian-based systems, update the chromium or chromium-browser package to the patched release available in Debian repositories. Enterprise administrators should deploy updates via their standard patch management systems and verify successful deployment across all client machines. Until updates are applied, restrict user access to untrusted websites and disable JavaScript in the browser for high-risk users, though these are incomplete mitigations. Refer to the official Chrome release notes at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html and the Chromium issue tracker at https://issues.chromium.org/issues/488585488 for implementation details and confirmation of the patch.
