In the Lustre file system before 2.12.3, the ptlrpc module has an
out-of-bounds access and panic due to the lack of validation for specific
fields of packets sent by a client. In the function
ldlm_cancel_hpreq_check, there is no lock_count bounds check.

| sbeattie | lustre was removed from the upstream staging tree in 4.18 (be65f9ed267fd7d8b3146b7c4be9ecdd3e0aa3ed) |
| cascardo | The affected code was never part of linux, as the staging driver was only the client side. |
