Unknown Unknown - Not Provided
Improper Error Handling and Memory Leak in Linux HFSplus Kernel Module

Publication date: 2025-12-24

Description
In the Linux kernel, the following vulnerability has been resolved: hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling Commit 55d1cbbbb29e ("hfs/hfsplus: use WARN_ON for sanity check") fixed a build warning by turning a comment into a WARN_ON(), but it turns out that syzbot then complains because it can trigger said warning with a corrupted hfs image. The warning actually does warn about a bad situation, but we are much better off just handling it as the error it is. So rather than warn about us doing bad things, stop doing the bad things and return -EIO. While at it, also fix a memory leak that was introduced by an earlier fix for a similar syzbot warning situation, and add a check for one case that historically wasn't handled at all (ie neither comment nor subsequent WARN_ON).

Executive Summary

This vulnerability involves the Linux kernel's hfs/hfsplus filesystem code where a sanity check was implemented using WARN_ON(), which caused warnings when encountering corrupted hfs images. Instead of just warning, the fix changes the code to properly handle the error by returning an error code (-EIO) and stops performing the bad operations. Additionally, a memory leak introduced by a previous fix was corrected, and a previously unhandled case was added to the checks.

Impact Analysis

The vulnerability could cause the Linux kernel to emit warnings and potentially perform improper operations when handling corrupted hfs filesystem images, which might lead to instability or unexpected behavior. The fix improves error handling and prevents memory leaks, thereby enhancing system stability and reliability when dealing with corrupted hfs images.
