Summary

In the Linux kernel, the amdgpu driver's BAR0 fallback read path, a workaround for SR-IOV virtual functions during early initialization, was applied more broadly than needed. The fix restricts this workaround to SR-IOV virtual functions only, where it is required.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: restrict BAR0 fallback read to SR-IOV VFs only The BAR0 fallback read path was introduced as a workaround for SR-IOV VFs where the VRAM aperture is not available during early init. Restrict this workaround to only SR-IOV VFs where it's needed. (cherry picked from commit d8a0affd207c813bd063fa2c27786f449eaf92b8)
