Use after free in WebRTC 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 corruption via use-after-free in Google Chrome's WebRTC implementation (versions prior to 146.0.7680.153) enables remote attackers to achieve arbitrary code execution through malicious HTML pages, requiring only user interaction. The vulnerability affects Chrome, Ubuntu, and Debian systems with a CVSS score of 8.8, though a patch is available.
Technical ContextAI
This vulnerability is rooted in CWE-416 (Use After Free), a memory safety defect where WebRTC code attempts to access memory that has been deallocated. WebRTC is a real-time communication protocol and framework implemented natively in Chromium-based browsers for peer-to-peer audio, video, and data streaming. The use-after-free occurs within WebRTC's memory management lifecycle, likely during connection establishment, teardown, or state transitions. An attacker exploits this by crafting HTML that triggers specific WebRTC operations in a sequence that causes the application to reference freed heap memory, corrupting the heap and potentially enabling code execution. The affected product is Google Chrome (Chromium project), tracked via Debian security advisories across 9 released versions.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later via the built-in auto-update mechanism (Settings > About > Check for updates) or manual download from https://www.google.com/chrome/. For Debian users, apply security updates from the Debian security repository (apt update && apt upgrade chromium). Until patching is completed, implement defense-in-depth measures: restrict access to untrusted websites by deploying web filtering and content security policies; consider using Chrome extensions that sandbox or restrict WebRTC functionality if patching is delayed; educate users to avoid clicking links from untrusted sources. Enterprise administrators should prioritize patching via managed deployment tools (GPO, MDM, Jamf) to ensure rapid coverage across the organization. Verify successful patching by confirming Chrome version in chrome://version/ shows 146.0.7680.153 or higher.
