Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix a NULL pointer dereference in amdgpu_dm_i2c_xfer()
When ddc_service_construct() 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
amdgpu_dm_i2c_xfer() call.
