CVE-2022-0247
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 · uneditedAn issue exists in Fuchsia where VMO data can be modified through access to copy-on-write snapshots. A local attacker could modify objects in the VMO that they do not have permission to. We recommend upgrading past commit d97c05d2301799ed585620a9c5c739d36e7b5d3d or any of the listed versions.
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 analysisA sensitive file, directory, or resource is created with permissions more open than it needs, so unintended users can read or modify it. Attackers look for exactly these loose defaults. Remediation is assigning the minimum permissions required and verifying them at install time and at runtime.

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.
dbcve · scoped2022-01-03
Any Fuchsia release or build dated 2022-01-03 or later (post-commit d97c05d2301799ed585620a9c5c739d36e7b5d3d)
- 1. Identify the current Fuchsia version in use by checking the system or build configuration
- 2. Navigate to the Fuchsia project repository at https://fuchsia.googlesource.com/fuchsia/
- 3. Obtain a Fuchsia release or build dated 2022-01-03 or later
- 4. Follow the standard Fuchsia upgrade procedure to deploy the newer version
- 5. Verify the upgrade by confirming the VMO copy-on-write behavior no longer allows unauthorized modification
