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
An integer overflow in sqfs_inode_size in Das U-Boot before 2025.01-rc1 occurs in the symlink size calculation via a crafted squashfs filesystem.

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
How this class of weakness works · CWE-190

An arithmetic operation produces a value too large for its type and wraps around to an unexpected — often tiny or negative — number. That miscalculated value then drives a memory allocation or a bounds check, opening the door to corruption. The fix is checked arithmetic and validating sizes before they're used.

Recommended fix High confidence

U-Boot 2025.01-rc1 (or any release after 2024.10)

  1. 1. Identify the current U-Boot version in use by checking the version string during boot or in the build configuration
  2. 2. Download or clone the U-Boot source code from the official repository: https://source.denx.de/u-boot/u-boot
  3. 3. Checkout the fixed version: 2025.01-rc1 or any version released after 2024.10
  4. 4. Review the patch at commit c8e929e5758999933f9e905049ef2bf3fe6b140d to understand the fix details
  5. 5. Rebuild U-Boot with the updated source code
  6. 6. Flash the newly built U-Boot image to the target device
  7. 7. Verify the new version is running correctly and test squashfs filesystem handling
Caveat Review release notes for any configuration or API changes between 2024.10 and 2025.01-rc1; test thoroughly in a non-production environment first
