Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: fix a NULL pointer dereference in amdgpudmi2c_xfer()

When ddcserviceconstruct() is called, it explicitly checks both the link type and whether there is something on the link which will dictate whether the pin is marked as hw_supported.

If the pin isn't set or the link is not set (such as from unloading/reloading amdgpu in an IGT test) then fail the amdgpudmi2c_xfer() call.
