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)","published_at":"2026-06-26T19:41:06.568000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/b37a978e6d8c33fbfa4abc5dcca4c7cfc6d01f22","https://git.kernel.org/stable/c/4ae3e16f4b3bf64140f773629b765d605ee079a9"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:52.348775Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2631ac1ac328189031d1aefbbd4929050f72fb23","version_start_inclusive":true,"version_end":"b37a978e6d8c33fbfa4abc5dcca4c7cfc6d01f22","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2631ac1ac328189031d1aefbbd4929050f72fb23:b37a978e6d8c33fbfa4abc5dcca4c7cfc6d01f22"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2631ac1ac328189031d1aefbbd4929050f72fb23","version_start_inclusive":true,"version_end":"4ae3e16f4b3bf64140f773629b765d605ee079a9","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2631ac1ac328189031d1aefbbd4929050f72fb23:4ae3e16f4b3bf64140f773629b765d605ee079a9"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"5.14","version_start_inclusive":true,"version_end":"5.14","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:5.14:5.14"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"5.14","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:5.14"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.0.10","version_start_inclusive":true,"version_end":"7.0.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.0.10:7.0.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.1","version_start_inclusive":true,"version_end":"*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.1:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://git.kernel.org/stable/c/b37a978e6d8c33fbfa4abc5dcca4c7cfc6d01f22","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/4ae3e16f4b3bf64140f773629b765d605ee079a9","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:41:06.568000Z","label":"CVE published","source":null}]}
