'Spoiler is the newest speculative attack affecting Intel's
micro-architecture. From a report:

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 Lubeck in
north Germany detail the attack in a new paper, 'Spoiler: Speculative
load hazards boost Rowhammer and cache attacks'. The paper [PDF] was
released this month and spotted by The Register. The researchers
explain that Spoiler is not a Spectre attack, so it is not affected by
Intel's mitigations for it, which otherwise can prevent other
Spectre-like attacks such as SplitSpectre.'
