Branch History Injection (BHI), a new variant of the Spectre V2 vulnerability affecting several Intel processors and a handful of Arm cores, was announced earlier this week by VUSec, the Systems and Network Security Group at Vrije Universiteit Amsterdam. Linux site Phoronix performed tests showing a 35% drop in performance on the affected processors by the new BHI mitigations.

Intel plans to release a security update for the company's affected processors but will take longer to produce due to the number of attacked processors. Readers will remember earlier this week that the Intel processors from the Haskell series are the most vulnerable of the company's chips. The Linux community has already initiated the mitigation to fix the affected CPUs on their operating system. It was very shortly after the announcement of the exploit that an update was already in effect.
