AI Analysis
Technical Summary
CVE-2026-91744 is a race condition vulnerability in the PlatformIntegration module of Google Chrome on Mac platforms before version 153.0.8010.47. Exploitation requires that the attacker already has compromised the renderer process and uses social engineering techniques to trick the user into visiting a maliciously crafted HTML page, which then can lead to disclosure of sensitive information. The vulnerability was publicly disclosed and patched by Google in a stable channel update.
Potential Impact
If exploited, this vulnerability could allow an attacker with control over the renderer process and the ability to socially engineer a user to leak sensitive information from the browser environment. The impact is limited to information disclosure and requires prior compromise of the renderer process and user interaction.
Mitigation Recommendations
Google has released an official stable channel update for Chrome that fixes this vulnerability in version 153.0.8010.47. Users should update to this version or later to remediate the issue. No additional mitigation is required beyond applying the official patch.
