12-18-25 Out of band updates - when available?

Hi everyone, just wanted to know when the out of band released on 12/18/25 for the MSMQ vulnerability

Thanks!

Thanks

These were already released on 12/18/2025 and should be appearing in console by now

Hi, I saw them in BigFix on the 19th, thank you!

This was previously released and details are here:

But yet, KB5071543 is not superseded. It is in the MS catalog but not in HCL content.

We do not supersede a security update (KB5071543) which has CVEs associated with it with a non-security update (KB5074974) which does not have any CVEs associated with it. This non-security update (KB5074974) released on 12/18/2025 mitigated a software bug with the Message Queuing (MSMQ) functionality. Thanks, Gus.
