Google Chrome: Memory corruption in HID component allows sandbox code execution
Summary
A memory corruption flaw in the HID component of Google Chrome before 156.0.8078.47 can be triggered by a crafted HTML page. A remote attacker can execute arbitrary code inside the browser sandbox. The victim must open the malicious page, but no privileges are required. NVD and Microsoft rate the issue CVSS 8.8.

- Google Chrome prior to 156.0.8078.47
- Windows and macOS: versions before 156.0.8078.48 (source versions differ, see sources)
- Chromium-based browsers that include the affected code, such as Microsoft Edge
- Linux: Chromium snap packages on Ubuntu (listed as Not affected for the chromium-browser package because the snap is used)
Fixed in
- Google Chrome 156.0.8078.48 or later for Windows and macOS
- Google Chrome 156.0.8078.47 or later for Linux
- Android: 156.0.8078.47 reportedly carries the same fixes
- Upstream: Chromium issue 505024593 is marked Fixed
Workaround
Unknown.
Exploitation
- No in-the-wild exploitation reported for this CVE.
- CISA Known Exploited Vulnerabilities: not listed according to a third-party source; not verified directly.
