📋 Description
In the Linux kernel, the following vulnerability has been resolved:
hfs: Replace BUG_ON with error handling for CNID count checks
In a06ec283e125 next_id, folder_count, and file_count in the super block info were expanded to 64 bits, and BUG_ONs were added to detect overflow. This triggered an error reported by syzbot: if the MDB is corrupted, the BUG_ON is triggered. This patch replaces this mechanism with proper error handling and resolves the syzbot reported bug.
