Race in Shared Storage in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Google Chrome prior to version 148.0.7778.96 contains a race condition in shared storage that allows a remote attacker with a compromised renderer process to leak cross-origin data through a crafted HTML page. The vulnerability requires user interaction and renderer compromise but can disclose sensitive information across origin boundaries, classified as medium severity by Chromium security team.
Technical ContextAI
This vulnerability exploits a race condition (CWE-362) in Chrome's shared storage implementation, likely affecting the Storage API or similar cross-origin storage mechanisms. The race condition emerges from improper synchronization when multiple processes or threads access shared storage resources concurrently. The attack requires compromising the renderer process first, which executes untrusted web content with limited privileges. The vulnerability allows the attacker to craft HTML that races against legitimate storage access to read data that should be isolated to different origins, bypassing Chrome's same-origin policy enforcement.
RemediationAI
Users should update Google Chrome to version 148.0.7778.96 or later immediately via the automatic update mechanism (Settings > About Chrome > Check for updates) or manual download from https://www.google.com/chrome. No workarounds are available for this race condition without patching, as it is inherent to the shared storage implementation. Organizations managing Chrome deployments should enforce the minimum version requirement through Group Policy (Windows: MinimumChromeVersion), MDM platforms (macOS/iOS), or CloudMDM (Chromebooks). The patch addresses the underlying synchronization flaw in shared storage access, eliminating the race window that enabled cross-origin data leakage.
