In the Linux kernel, the following vulnerability has been resolved:
btrfs: clear free space tree creation state on rebuild failure
btrfs rebuild free space tree() sets BTRFS FS CREATING FREE SPACE TREE
before rebuilding the free space tree. Several error paths return
without clearing this flag.
The transaction restart failure path can leave the flag set on a live
filesystem, causing delayed reference processing to be skipped. Clear it
on all free space tree rebuild failure paths. Keep
BTRFS FS FREE SPACE TREE UNTRUSTED set, since a failed rebuild leaves
the free space tree untrusted. Callers must fall back to extent-tree
caching.
