CVE-2026-46175

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

Description An inconsistency occurs in the f2fs file system during Foreground Garbage Collection (FGGC) node block migration. The Garbage Collection process fails to clear the dentry and fsync marks during migration, which causes the file system check (fsck) tool to incorrectly interpret migrated node blocks as data written via fsync. In contrast, Background Garbage Collection (BGGC) handles this via the f2fs sync node pages() function, which ensures these marks are cleared before writing.

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