"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: free mapping node on duplicate reloc root insert\n\n__add_reloc_root() allocates a mapping_node before inserting it into\nrc->reloc_root_tree. If rb_simple_insert() finds an existing entry, it\nreturns the existing rb_node and leaves the newly allocated node unlinked.\n\nThe error path then returns -EEXIST without freeing the new node. Since\nthe node was never inserted into reloc_root_tree, the later cleanup in\nput_reloc_control() cannot find it either.\n\nFree the newly allocated node before returning -EEXIST.\n\nThe callers currently assert that -EEXIST should not happen, so this is a\ndefensive cleanup for an unexpected duplicate insert path. If the path is\never reached, the local allocation should still be released."
