Use after free in Blink 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's Blink rendering engine prior to version 146.0.7680.153 can be triggered through a malicious HTML page, potentially enabling remote code execution. An unauthenticated attacker requires only user interaction to exploit this use-after-free vulnerability across network boundaries. A patch is available for affected Chrome, Ubuntu, and Debian users.
Technical ContextAI
This vulnerability resides in the Blink rendering engine (Chromium's fork of WebKit), which parses and renders HTML, CSS, and JavaScript in Google Chrome. The root cause is classified as CWE-416 (Use After Free), a memory safety flaw where the renderer attempts to access heap-allocated objects after they have been freed, potentially leading to information disclosure or code execution. Attackers can trigger this flaw by crafting malicious HTML pages that manipulate the Document Object Model (DOM) in a way that causes Blink to free memory prematurely while maintaining stale pointers. The vulnerability affects Chrome versions below 146.0.7680.153 across all supported platforms (Windows, macOS, Linux), as confirmed by the Chromium Issues tracker (issues.chromium.org/issues/487117772). The affected product is Google Chrome (CPE: cpe:2.3:a:google:chrome), with specific vulnerable versions documented in the EUVD database as all releases prior to 146.0.7680.153.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later via the built-in update mechanism (Settings > About > Chrome, or manual download from https://www.google.com/chrome/). For Debian-based systems, apply security updates via apt-get update && apt-get upgrade once patches are released. Users unable to update immediately should disable JavaScript execution in less-trusted browser contexts, restrict browsing to known-safe websites, and consider using sandboxing features (such as Windows Sandbox or virtual machines) when accessing untrusted content. Enterprise deployments should enforce automatic updates via group policies (Windows) or MDM solutions and monitor for any exploitation attempts in web server logs. The vendor advisory at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html confirms patch availability as of March 2026.
