In the Linux kernel, the following vulnerability has been resolved: btrfs: reject root items with dropprogress and zero droplevel BUG When recovering relocation at mount time, mergerelocroot and btrfsdropsnapshot both use BUGONlevel == 0 to guard against an impossible state: a non-zero dropprogre...

CVE-2026-43046

CVE-2026-43046 affects the Linux kernel, specifically btrfs relocation logic where a non-zero drop_progress with drop_level == 0 can be observed in a read-back root_item. The root_item invariant is now validated in the tree-checker when reading from disk: if drop_progress.objectid is non-zero, dr...
