CVE-2023-52588

Data corruption via missing page GC flag

Published Mar 6, 2024 · Updated Aug 5, 2026

Data corruption in Linux kernel F2FS 3.8 through 6.7.3 allows local users to corrupt migrated file data after sudden power loss. The set_cluster_dirty, __clone_blkaddrs, and redirty_blocks paths mark migrated pages dirty but omit set_page_private_gcing, so checkpoints can persist data and node updates out of order. Reachability requires an F2FS volume, block migration through the affected compression, cloning, or decompression paths, and sudden power-off recovery.
