Software Bug in Linux Kernel Affecting JFS Inodes Handling

CVE-2025-37925

Summary

This vulnerability arises from a flaw in the Linux Kernel's handling of JFS inodes, specifically when the function 'clear_inode()' attempts to finalize an inode of an unsupported type. Inodes from 5 to 15 are reserved for future use and should not be encountered in a valid filesystem, leading to a runtime error. The vulnerability has been addressed in updates, but users should verify their kernel version to ensure they are protected against potential exploitation.
