Hi all,

# Description
A NULL Pointer Dereference bug in nvmet_setup_auth
(drivers/nvme/target/auth.c) can be triggered remotely to cause a DoS.
Since the bug occurs in the authentication feature, it can be easily
triggered by an unauthorized client in the pre-auth stage.
Versions affected - v6.0-rc1 to v6.0-rc3 (fixed in v6.0-rc4).

Meta-comment, why are CVE's being assigned for issues found, and then
fixed, in development kernel releases?  Who assigned this CVE, MITRE or
someone else?

This information used to be available for "reserved" CVEs in the JSON
data in [1], but now that that's retired I'm not sure this is made
public anywhere.

So if we don't know who allocated it, we can't know who to ask to get it
revoked?

{sigh}

Yet-another reason why I hate CVEs...
