      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix inode list leak during backref walking at resolve_indirect_refs()\n\nDuring backref walking, at resolve_indirect_refs(), if we get an error\nwe jump to the 'out' label and call ulist_free() on the 'parents' ulist,\nwhich frees all the elements in the ulist - however that does not free\nany inode lists that may be attached to elements, through the 'aux' field\nof a ulist node, so we end up leaking lists if we have any attached to\nthe unodes.\n\nFix this by calling free_leaf_list() instead of ulist_free() when we exit\nfrom resolve_indirect_refs(). The static function free_leaf_list() is\nmoved up for this to be possible and it's slightly simplified by removing\nunnecessary code.",
