In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix reservation leak in some error paths when inserting inline extent

If we fail to allocate a path or join a transaction, we return from cow file range inline() without freeing the reserved qgroup data, resulting in a leak. Fix this by ensuring we call btrfs qgroup free data() in such cases.
