8.8 HIGH

📋 TL;DR

This is a use-after-free vulnerability in Google Chrome's Sharing feature on macOS that allows remote attackers to potentially exploit heap corruption. Attackers can craft malicious HTML pages that, when visited by users who perform specific interactions, could lead to arbitrary code execution. Affects Chrome users on macOS who haven't updated to patched versions.

💻 Affected Systems

Products:
  • Google Chrome
Versions: Versions prior to 101.0.4951.41

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with the privileges of the Chrome process, potentially leading to full system compromise, data theft, or ransomware deployment.

🟠

Likely Case

Browser crash (denial of service) or limited information disclosure; successful RCE requires specific user interaction and exploit reliability.

🟢

If Mitigated

No impact if Chrome is fully patched or if users avoid suspicious websites and interactions.

🌐 Internet-Facing: HIGH - Attackers can host malicious pages on the internet and target users through phishing or compromised legitimate sites.
🏢 Internal Only: MEDIUM - Risk exists if internal users visit malicious internal pages, but attack surface is smaller than internet-facing.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires convincing users to engage in specific interactions on a malicious page; no public exploit code is known.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 101.0.4951.41 and later
