CVE-2026-68442

CVE-2026-68442 describes a Linux kernel btrfs bug where splitting extent maps incorrectly propagates EXTENT_FLAG_LOGGING to new split maps. The local flags copy was used for splits, while a later change cleared the flag on em->flags, so a split map being logged could be freed with the flag sti...
