CVE-2025-39779

CVE-2025-39779 affects the Linux kernel’s btrfs subpage handling. The bug arises when btrfs_subpage_set_writeback() clears PAGECACHE_TAG_TOWRITE on a folio that still has dirty pages, breaking writeback ordering guarantees (e.g., btrfs_wait_ordered_extents()) and causing potential failures in zon...
