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 · unedited
Release of Invalid Pointer or Reference vulnerability was discovered in fs/inode/fs_inoderemove code of the Apache NuttX RTOS that allowed root filesystem inode removal leading to a debug assert trigger (that is disabled by default), NULL pointer dereference (handled differently depending on the target architecture), or in general, a Denial of Service. This issue affects Apache NuttX RTOS: from 10.0.0 before 12.10.0. Users of filesystem based services with write access that were exposed over the network (i.e. FTP) are affected and recommended to upgrade to version 12.10.0 that fixes the issue.

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.

Recommended fix High confidence

12.10.0

  1. 1. Identify all NuttX deployments running versions >= 10.0.0 and < 12.10.0
  2. 2. Review the current implementation of fs/inode/fs_inoderemove in your codebase for any local modifications
  3. 3. If using a package manager or build system for NuttX, update to version 12.10.0
  4. 4. If building from source, fetch the updated source code from https://github.com/apache/nuttx/releases/tag/12.10.0 or the master branch at commit corresponding to 12.10.0
  5. 5. Rebuild the NuttX image with the updated code
  6. 6. Test the filesystem functionality, particularly inode operations and root filesystem operations
  7. 7. Redeploy the updated NuttX image to all affected devices
  8. 8. If using network-exposed filesystem services (e.g., FTP), verify the fix prevents the invalid inode removal
