Security readout for executives and security teams
Plain-English summary
CVE-2022-3048 is a Chrome OS lockscreen weakness fixed before version 105.0.5195.52. Someone with physical access could bypass navigation restrictions while the device was locked. It matters most for shared, kiosk, education, retail, and lost or unattended Chrome OS devices.
Executive priority
Treat this as a targeted physical-access risk, not a mass remote compromise. Patch or retire affected Chrome OS devices promptly, with priority for fleets in public, shared, or mobile settings where unattended access is plausible.
Technical view
The CVE describes an inappropriate implementation in the Chrome OS lockscreen, mapped to CWE-863. The CVSS vector is physical access, low complexity, no privileges or user interaction, unchanged scope, with high confidentiality, integrity, and availability impact. Sources identify Chrome OS before 105.0.5195.52 as affected.
Likely exposure
Exposure is most likely where Chrome OS devices remain below 105.0.5195.52 and can be physically accessed by untrusted people. The provided affected-product metadata is broad, so asset validation should focus on Chrome OS version evidence rather than assuming all Chrome installations are exposed.
Exploitation context
The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Exploitation requires physical access to the device, reducing internet-scale risk but increasing concern for unattended, shared, or stolen endpoints.
Researcher notes
The public description is concise and does not include implementation detail. Avoid broad Chrome desktop assumptions: the vulnerability is specifically described in Chrome OS lockscreen behavior before 105.0.5195.52. Active exploitation is not supported by the provided sources.
Mitigation direction
- Update Chrome OS devices to 105.0.5195.52 or later where applicable.
- Check Google and device-management guidance for any model-specific remediation details.
- Prioritize shared, kiosk, classroom, retail, and executive-travel Chrome OS devices.
- Reduce unattended physical access until affected devices are updated.
- Review lost-device and remote-wipe processes for managed Chrome OS fleets.
Validation and detection
- Inventory Chrome OS devices and record OS version for each endpoint.
- Flag devices running Chrome OS versions before 105.0.5195.52.
- Confirm update status through endpoint or Chrome enterprise management records.
- Verify lockscreen policies are managed consistently across shared-device groups.
- Check incident records for lost, stolen, or unattended affected devices.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
