Linux Kernel Vulnerability in HFSPlus Affecting Special Inodes

CVE-2026-43268

What is CVE-2026-43268?

A vulnerability has been identified in the Linux kernel related to the handling of HFSPlus file types. This issue arises when certain special inodes are incorrectly treated as regular files.

This fix enhances the integrity of the file system and mitigates potential exploitation risks that could lead to unauthorized access or manipulation of file data.
