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 thelink type and whether there is something on the link which willdictate whether the pin is marked as hw_supported.If the pin isn t set or the link is not set (such as fromunloading/reloading amdgpu in an IGT test) then fail theamdgpu_dm_i2c_xfer() call.
