CVE-2026-53368: In the Linux kernel, the following vulnerability has been resolved: f2fs: fix fsck inconsistency caused by incorrect na
Summary
A vulnerability in the Linux kernel's f2fs (flash-friendly file system) allows inconsistent file system states because the function f2fs_need_dentry_mark() reads flag information without proper synchronization (locking mechanisms that prevent simultaneous access) with checkpoint operations. This can cause file system checking tools to detect that an inode (a data structure representing a file) has already been saved to disk but is marked with an inconsistent flag, which creates a logical contradiction.
Solution / Mitigation
This patch moves the set_dentry_mark() function call into __write_node_folio() and protects it with the sbi->node_write lock to ensure that flag updates happen with proper synchronization.
