      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: reject zero bucket types in crush_decode\n\nCRUSH bucket type 0 is reserved for devices.  The mapper relies on\nthat invariant and uses type 0 to identify leaf devices.\n\nIf crush_decode() accepts a bucket with type 0, a malformed CRUSH map\ncan make the mapper treat a negative bucket ID as a device and pass it\nto is_out(), which then indexes the OSD weight array with a negative\nvalue.\n\nReject zero bucket types while decoding the CRUSH map so the invalid\nstate never reaches the mapper.",
