Vulnerability Report
Generated by CyberWatcher
Description
A flaw was found in the Linux kernel's btrfs filesystem. When the `__add_reloc_root()` function attempts to insert a duplicate mapping node into the `reloc_root_tree`, the newly allocated node is not properly freed. This oversight can lead to a memory leak, potentially causing resource exhaustion and a Denial of Service (DoS) over an extended period if this unexpected path is triggered.
