Description OSIDB Bzimport 2026-08-10 12:34:14 UTC 
In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix root leak if its reloc root is unexpected in merge_reloc_roots()

If we have an unexpected reloc_root for our root, we jump to the out label
but never drop the reference we obtained for root, resulting in a leak.
Add a missing btrfs_put_root() call.
