Spectre is back from the dead
 

Harder to kill than Dracula

The embarrassing defect in Intel CPUs Spectre appears to have made a comeback.

It appears that someone has managed to gather a ring belonging to idiot that created the flaw, chanted over a grave at midnight and rebuilt the whole crisis again from the dust of its corpse.

Security research group VUSec and Intel confirmed the existence of a new speculative execution vulnerability labeled branch history injection (BHI).

Classified as a by-product of Spectre V2, BHI is a proof-of-concept exploit capable of leaking arbitrary kernel memory on Intel CPUs. As a result, sensitive data such as passwords can be extracted. Intel processors released in the past few years, which includes its latest 12th-generation Alder Lake processors, are said to be affected.

Some ARM silicon is vulnerable to the exploit, although AMD CPUs seem to remain immune to potential BHI attacks.
