"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Avoid NULL dereference in dc_dmub_srv error paths\n\nIn dc_dmub_srv_log_diagnostic_data() and\ndc_dmub_srv_enable_dpia_trace().\n\nBoth functions check:\n\n if (!dc_dmub_srv || !dc_dmub_srv->dmub)\n\nand then call DC_LOG_ERROR() inside that block.\n\nDC_LOG_ERROR() uses dc_dmub_srv->ctx internally. So if\ndc_dmub_srv is NULL, the logging itself can dereference a\nNULL pointer and cause a crash.\n\nFix this by splitting the checks.\n\nFirst check if dc_dmub_srv is NULL and return immediately.\nThen check dc_dmub_srv->dmub and log the error only when\ndc_dmub_srv is valid.\n\nFixes the below:\n../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)\n../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)"
