File Type Handling Issue in Linux Kernel BFS by Vendor
CVE-2025-68266

Currently unrated

What is CVE-2025-68266?

A vulnerability in the Linux kernel's BFS file system can lead to corrupt inode data, affecting file type reconstruction when loading files from disk. The issue arises due to potential corruption of the 'mode' and 'attributes' fields in the inode structure, specifically regarding the S_IFMT bits being left uninitialized. This could lead to incorrect interpretations of file types, compromising data integrity. Proper validation is required to ensure that only the defined types, BFS_VREG or BFS_VDIR, are recognized, thus safeguarding against misclassification and operational failures.
