CVE-2022-3048
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInappropriate implementation in Chrome OS lockscreen in Google Chrome on Chrome OS prior to 105.0.5195.52 allowed a local attacker to bypass lockscreen navigation restrictions via physical access to the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA local attacker with physical access to a Chrome OS device can bypass lockscreen navigation restrictions due to an inappropriate implementation in the Chrome OS lockscreen, allowing unauthorized access to the device without proper authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Chrome or Chromium versionNavigate to chrome://settings/help or run 'google-chrome --version' or 'chromium-browser --version' in terminalAffected if Version is below 105.0.5195.52
-
Identify the operating systemRun 'uname -a' or check system information to determine if running Chrome OS or Fedora 37Affected if Running Chrome OS of any version or Fedora 37 with Chrome installed
-
Verify lockscreen is enabledCheck Chrome OS settings under 'Lock screen' or on Fedora check Screen Lock settings in system preferencesAffected if Lockscreen protection is configured and active
-
Confirm physical access threat modelDetermine if device is used in environments where unauthorized physical access is a concern (shared/public devices)Affected if Device is accessible to multiple users or located in public areas
System is affected if Chrome or Chromium version is below 105.0.5195.52 AND lockscreen is enabled, particularly on Chrome OS or Fedora 37 systems where physical access by untrusted users is possible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
