CVE-2025-11210

Description

Side-channel information leakage in Tab in Google Chrome prior to 141.0.7390.54 allowed a remote attacker who convinced a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)

        <h2>Attack Scenario</h2>
        <p>1. Attacker creates a malicious HTML page</p>
        <p>2. User visits the page and performs specific UI gestures</p>
        <p>3. Page collects side-channel timing information</p>
        <p>4. Attacker uses information to perform UI spoofing</p>

            - Measurements taken: ${measurements.length}
            - Average timing: ${avgTime.toFixed(4)}ms
            - Min: ${Math.min(...measurements).toFixed(4)}ms
            - Max: ${Math.max(...measurements).toFixed(4)}ms
            
            This timing information could be used to:
            1. Detect user tab switching patterns
            2. Infer sensitive information through timing variations
            3. Execute UI spoofing attacks based on observed behavior
            
            Mitigation: Upgrade to Chrome 141.0.7390.54 or later`;
