Are the security issues posed by GPU-Passthrough under or over exaggerated?

Are the security concerns mainly from using the iommu acs patch

Yes

Provided you don’t use the ACS override patch which efficiently cripples IOMMU, the GPU can not access the hosts memory due to the hardware limitations imposed by IOMMU.

Edit: sorry, was the wrong reply.
