CVE-2022-3312

Managed-device restriction bypass via unvalidated VPN input

Published Nov 1, 2022 · Updated May 6, 2025

Insufficient input validation in Google Chrome before 106.0.5249.62 allows physically proximate attackers to bypass ChromeOS restrictions. The VPN component accepts untrusted input without sufficient validation, but Google has not disclosed the rejected condition or affected processing locus. Physical access to a managed, locked ChromeOS device is required, and the reported consequence is limited to bypassing administrator-enforced device restrictions.
