If rb_simple_insert() finds an existing entry, it returns the existing rb_node and leaves the newly allocated node unlinked.</p> <p>The error path then returns -EEXIST without freeing the new node. Since the node was never inserted into reloc_root_tree, the later cleanup in put_reloc_control() cannot find it either.</p> <p>Free the newly allocated node before returning -EEXIST.</p> <p>The callers currently assert that -EEXIST should not happen, so this is a defensive cleanup for an unexpected duplicate insert path. If the path is ever reached, the local allocation should still be released.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>btrfs: free mapping node on duplicate reloc root insert</p> <p>__add_reloc_root() allocates a mapping_node before inserting it into rc-&gt;reloc_root_tree.
