Hello,
I'm trying to figure out the security impact here:
> That warning is triggered by the following statement:
>
> WARN_ON(lrbp->cmd);
This is just a fix to silence a warning. How is this worthy of a CVE? What was
the criteria here?
If there are security implications of not nullifying `lrbp->cmd`, shouldn't they
be noted in the CVE description?
If this just a fix to the warning, this CVE should be rejected.

CVE descriptions come directly from the kernel changelog text. If you
wish them to say something else, please submit a patch against that text
and we can apply that.

If userspace can trigger a WARN_ON() then the machine can be rebooted if
panic-on-warn is enabled, and so it requires a CVE assignment.
