In theory when properly configured the DSP or GPU should be unable to touch system RAM outside of buffers that are specifically assigned to them.
I'm not very familiar with the status of IOMMU on Android devices.
If the US government hadn't sanctioned Huawei, we could have an alternative to these chips.

From Apple's perspective Qualcomm has been insufficient for a long time for many reasons, the security issues here would only be one of the many factors involved in the decision to do their own development. For what it is worth, a modern chip as complex as the A* series is essentially guaranteed to have vulnerabilities. Maybe not 400, but definitely not 0.
This is a thing I think people constantly underestimate... Intel's cores are not necessarily dramatically more broken than everyone else's chips, they just pay for more auditing and public research.

> they just pay for more auditing and public research. Who is Intel paying to audit their chips?
Anyone who wants to report something via their bug bounty program. https://www.intel.com/content/www/us/en/security-center/bug-...
Shouldn't proper IOMMU usage prevent this? In theory when properly configured the DSP or GPU should be unable to touch system RAM outside of buffers that are specifically assigned to them. I'm not very familiar with the status of IOMMU on Android devices.

> they just pay for more auditing and public research. Did Intel finance the research that turned up any of the major headline vulnerabilities over the last few years (meltdown, spectre)?
