Subject: Re: CVE-2024-26908: x86/xen: Add some null pointer checking to smp.c

Hi,

I'd like to dispute CVE-2024-26908: the issue fixed by upstream commit
3693bb4465e6e32a204a5b86d3ec7e6b9f7e67c2 can in no way be triggered by
an unprivileged user or by a remote attack of the system, as it requires
hotplug of (virtual) cpus to the running system. This can be done only by
either a host admin or by an admin of the guest which might suffer the
out-of-memory situation.

Please revoke this CVE.

Juergen
