no network or remote peer data is involved.\nAC:L - The attacker controls both sides of the race — they fill the filesystem to force the `btrfs_reserve_extent()` ENOSPC failure and issue the concurrent dirtying/writeback that leaves the ordered extent still in the io tree — and the upstream reproducer (generic/750) crashes with \"very high chance\"; subpage btrfs needs no kernel CONFIG, only a 4K-sector filesystem on a 64K/16K-page kernel, and the compressed-writeback variant exists on all page sizes.\nPR:L - Any unprivileged local user with write access to a btrfs filesystem (e.g. /home, /var/tmp) can create prealloc extents, drive the filesystem to ENOSPC, and dirty pages; no capabilities and no mount privileges are required.\nUI:N - Exploitation needs only the attacker's own writes on an already-mounted filesystem; writeback is initiated by the kernel (shrink_delalloc/reclaim worker) with no victim action.\nS:U - The corruption is confined to kernel memory and the btrfs filesystem within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The double `btrfs_remove_ordered_extent()`/`btrfs_put_ordered_extent()` frees the ordered-extent slab object while its embedded `btrfs_work` remains linked, giving a use-after-free on a sprayable kmem_cache object, and the duplicated extent/metadata accounting can hand the same on-disk extent to two files, exposing other users' data.\nI:H - The bug yields workqueue and rb-tree list corruption (re-INIT of a linked node plus double `list_add_tail`, `rb_erase` on a cleared node) and a UAF write primitive, plus doubled delalloc metadata release and `nr_ordered_extents` underflow that corrupt on-disk space accounting.\nA:H - The upstream report shows a WARNING followed by a NULL pointer dereference in `process_one_work` and \"Kernel panic - not syncing: Oops: Fatal exception\";
