vulnerability analysis and mitigation

A side-channel information leakage vulnerability in Storage (CVE-2025-11207) was discovered in Google Chrome versions prior to 141.0.7390.54. The vulnerability was reported by Alesandro Ortiz on June 27, 2025, and was officially patched in the Chrome stable channel update released on September 30, 2025. This security issue affects Chrome browsers across Windows, Mac, and Linux platforms, as well as ChromeOS devices and other Chromium-based browsers like Microsoft Edge (Chrome Releases, Ubuntu Security).

The vulnerability is classified as a Medium severity issue with a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N). The flaw allows potential attackers to perform arbitrary read/write operations through a crafted HTML page, specifically targeting the browser's storage mechanisms (Rapid7).

The vulnerability enables remote attackers to potentially access sensitive information through side-channel attacks targeting the browser's storage system. This could lead to unauthorized data exposure and compromise of user privacy (Ubuntu Security).

The vulnerability has been patched in Chrome version 141.0.7390.54 and later releases. Users are advised to update their Chrome browsers to the latest version. The fix has also been incorporated into other Chromium-based browsers, including Microsoft Edge and various Linux distributions such as Ubuntu and Debian (Chrome Releases, Debian Security).
