  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Avoid NULL dereference in dc_dmub_srv error paths  In dc_dmub_srv_log_diagnostic_data() and dc_dmub_srv_enable_dpia_trace().  Both functions check:    if (!dc_dmub_srv || !dc_dmub_srv-\u003edmub)  and then call DC_LOG_ERROR() inside that block.  DC_LOG_ERROR() uses dc_dmub_srv-\u003ectx internally. So if dc_dmub_srv is NULL, the logging itself can dereference a NULL pointer and cause a crash.  Fix this by splitting the checks.  First check if dc_dmub_srv is NULL and return immediately. Then check dc_dmub_srv-\u003edmub and log the error only when dc_dmub_srv is valid.  Fixes the below: ../display/dc/dc_dmub_srv.c:962 dc_dmub_srv_log_diagnostic_data() error: we previously assumed 'dc_dmub_srv' could be null (see line 961) ../display/dc/dc_dmub_srv.c:1167 dc_dmub_srv_enable_dpia_trace() error: we previously assumed 'dc_dmub_srv' could be null (see line 1166)",
