Inconsistency Vulnerability in F2FS for Linux Kernel by Linux Foundation

CVE-2025-38164

What is CVE-2025-38164?

This vulnerability in the F2FS (Flash-Friendly File System) implemented in the Linux kernel can cause inconsistencies between the Segment Information Table (SIT) and the Superblock Summary Area (SSA). It arises when the garbage collector attempts to migrate blocks from an open section without verifying if the SSA is up to date, potentially leading to system failures and filesystem integrity issues. Patches have been introduced to enforce checks that skip block migration for opened sections, thereby preventing these inconsistencies and enhancing the reliability of file operations.
