- Summary
- btrfs: fix root leak if its reloc root is unexpected in merge_reloc_roots()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix root leak if its reloc root is unexpected in mergerelocroots()
If we have an unexpected relocroot 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 btrfsput_root() call.
