Recommendation:
Intel recommends following the steps below to address these issues:
Restrict untrusted usage of Intel® DSA/IAA devices on impacted Intel® 4th Generation and 5th Generation Xeon® scalable processors, from VM guest or 3rd party application.
Intel has worked with the OS vendor to provide an updated Kernel to mitigate this issue, by disallowing direct access to Intel® DSA and IAA v1.0 devices by untrusted software. Intel recommends using the upstream or LTS Linux kernel with the updated driver containing mitigations. Please contact your OS vendor for updates.
In addition, Intel will be updating DSA and TAA libraries to work with the updated kernel version and recommends updating them so they will work with the updated driver. Please see the guidance doc:Intel® Data Streaming Accelerator and Intel® In-Memory Analytics Accelerator Error Reporting
