    Phoronix: CrossTalk/SRBDS Shows Possibility Of Leaking Information Across Physical CPU Cores

    This morning I noted CrossTalk / SRBDS as the newest side-channel vulnerability following Intel's monthly security advisories being sent out. It turns out Intel broke their own embargo on the disclosure and I happened to spot it quickly before they retracted it. In the hours since, the university researchers behind this CrossTalk vulnerability reached out and have provided an embargoed copy of the whitepaper. As of now, the formal disclosure time has passed so information on this new side-channel Intel CPU vulnerability is public and it shows for the first time that speculative execution can enable attackers to leak sensitive information across physical cores on Intel CPUs.

          This one seems specific to Intel. It was also initially discovered 2 years ago.

            It's specific to the design of the Intel chips. No one else is affected.
