Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the hfs component where the use of BUG ON to detect overflows in next id, folder count, and file count within the super block info can be triggered if the MDB (Master Directory Block) is corrupted. This leads to a system crash instead of graceful error handling.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
