The OpenBSD project announced today plans to disable support for Intel CPU hyper-threading due to security concerns regarding the theoretical threat of more "Spectre-class bugs." Hyper-threading (HT) ...

As we've come to learn recently, there are four new hardware vulnerabilities that affect Intel processors. These new flaws allow attackers to leak confidential data by exploiting microarchitectural ...

Intel has shipped Hyper-Threading CPUs for well over a decade, even subtracting the Core 2 era when the technology wasn't used. For most of that time, Hyper-Threading has been a technology that 'just ...

A new security report indicates issues with Hyper-Threading can leak cryptographic information in certain cases, but evidence points against this being a Spectre or Meltdown-class failure. Share on ...

Four new vulnerabilities have been discovered in Intel processors that can be exploited via speculative execution side-channel attacks called RIDL, Fallout, and ZombieLoad. These vulnerabilities allow ...

Unfortunately, disabling hyper threading seems to be the most reasonable option on modern systems. The Intel processors in them can not be trusted to maintain isolation between processes otherwise, ...
