What is CVE-2025-38663?

A vulnerability in the nilfs2 file system of the Linux kernel allows invalid file types to be processed when reading inodes, potentially leading to malfunctions and assertion failures. This issue can cause the virtualization file system (vfs) to improperly handle inode data, resulting in filesystem errors that may affect system stability and performance. A proper sanity check has been introduced to reject invalid file types, ensuring more robust and secure file handling within the system.
