drivers/gpu/drm/amd/display/modules/hdcp/hdcp1_execution.c:33:33: error: Buffer is accessed out of bounds

[David Binderman]

Hello there,

linux-5.6-rc1/drivers/gpu/drm/amd/display/modules/hdcp/hdcp1_execution.c:33:33: error: Buffer is accessed out of bounds: hdcp->auth.msg.hdcp1.bksv [bufferAccessOutOfBounds]

Source code is

   memcpy(&n, hdcp->auth.msg.hdcp1.bksv, sizeof(uint64_t));

Field bksv is only five bytes long. Suggest code rework.

Regards

David Binderman
