  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix fsck inconsistency caused by FGGC of node block\n\nDuring FGGC node block migration, fsck may incorrectly treat the\nmigrated node block as fsync-written data.\n\nThe reproduction scenario:\nroot@vm:/mnt/f2fs# seq 1 2048 | xargs -n 1 ./test_sync // write inline inode and sync\nroot@vm:/mnt/f2fs# rm -f 1\nroot@vm:/mnt/f2fs# sync\nroot@vm:/mnt/f2fs# f2fs_io gc_range // move data block in sync mode and not write CP\n  SPO, \"fsck --dry-run\" find inode has already checkpointed but still\n  with DENT_BIT_SHIFT set\n\nThe root cause is that GC does not clear the dentry mark and fsync mark\nduring node block migration, leading fsck to misinterpret them as\nuser-issued fsync writes.\n\nIn BGGC mode, node block migration is handled by f2fs_sync_node_pages(),\nwhich guarantees the dentry and fsync marks are cleared before writing.\n\nThis patch move the set/clear of the fsync|dentry marks into\n__write_node_folio to make the logic clearer, and ensures the\nfsync|dentry mark is cleared in FGGC.",
