I love the comments, especially proposed DILDO (damaging Intel leak data option) name for the 'feature'. LOL
That's the same exploit:

Quote:
The researchers have named their attack NetCAT, short for Network Cache ATtack. Their research is prompting an advisory for Intel that effectively recommends turning off either DDIO or RDMA in untrusted networks. The researchers say future attacks may be able to steal other types of data, possibly even when RDMA isn't enabled. They are also advising hardware makers do a better job of securing microarchitectural enhancements before putting them into billions of real-world servers.

Another issue with these vulnerabilities especially with those with private clouds is the risk of data breach from one container to another. One system could be exposed to external networks and can access data from a different container that would be for internal use only. IDK why people say that they are basically unaffected by this. If only you know how many CIOs and CTOs are scratching their heads thinking how many more vulnerabilities would be coming up. Especially with fixes with performance impact, client facing companies rely on their capacity planning for purchases which are done in advance. You can't just order a server like a laptop and get it delivered next day. With Epyc being cheaper and better performing, IDK how the long term sales projections are.
