Microsoft issued a security advisory about these vulnerabilities on June 14, 2022. So please read on before you rush to update your system(s). And there are known performance issues related to applying the updates or disabling the Intel Hyper-Threading Technology. Well, maybe there are good reasons, but the number of users that would have to worry about these vulnerabilities is relatively small. The normal gut reaction would be to install out of band updates as soon as possible. Microsoft wouldn’t be releasing the updates ahead of the regular cycle without good reason, would it? Microsoft has released out of band updates for information disclosure vulnerabilities in Intel CPUs.
