In the Linux kernel, the following vulnerability has been resolved:

libceph: reject zero bucket types in crush_decode

CRUSH bucket type 0 is reserved for devices. The mapper relies on that invariant and uses type 0 to identify leaf devices.

If crush_decode() accepts a bucket with type 0, a malformed CRUSH map can make the mapper treat a negative bucket ID as a device and pass it to is_out(), which then indexes the OSD weight array with a negative value.

Reject zero bucket types while decoding the CRUSH map so the invalid state never reaches the mapper.
