Thread regarding Qualcomm Inc. layoffs

Do QCOM processors have the security issue?

Haven't heard from QCOM yet, but a news article said ARM cores are affected. Doesn't QCOM use ARM cores? Trouble ahead?

"We have empirically verified the vulnerability

of several Intel processors to Spectre attacks, including

Ivy Bridge, Haswell and Skylake based processors.

We have also verified the attackā€™s applicability

to AMD Ryzen CPUs. Finally, we have also successfully

mounted Spectre attacks on several Samsung and

Qualcomm processors (which use an ARM architecture)

found in popular mobile phones."

There are actually three separate but related "bugs" which affect Intel, AMD, and ARM CPUs in different ways. Intel, which does the most speculative prefetching, is affected the most. Cores from ARM do the least speculative prefetching. Apple and Qualcomm which have architectural licenses from ARM have proprietary implementations and no one knows how vulnerable they really are.
