All Intel chips open to new Spoiler non-Spectre attack: Don't expect a quick fix

Researchers have discovered a new flaw affecting all Intel chips due to the way they carry out speculative execution for CPU performance gains.

Like the Spectre and Meltdown attacks revealed in January 2018, Spoiler also abuses speculative execution in Intel chips to leak secrets.

However, it targets a different area of the processor called the Memory Order Buffer, which is used to manage memory operations and is tightly coupled with the cache.

Researchers from Worcester Polytechnic Institute, Massachusetts, and the University of Lübeck in north Germany detail the attack in a new paper, 'Spoiler: Speculative load hazards boost Rowhammer and cache attacks'. The paper was released this month and spotted by The Register.
