As the mbwu_state is allocated after\ncomp->cfg is set, and is also under mpam_list_lock, only the first\npointer needs checking.","published_at":"2026-06-26T19:40:40.694000Z","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/8eb6dc76eeae5302c0d885906a0e469ef9630a59","https://git.kernel.org/stable/c/6ccbb613b42a1f1ba7bfd547a148f644a902a25c"],"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":"2026-06-28T23:30:51.545322Z"},"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":"3bd04fe7d807bbdcfe75b29ca82fae4e2d7dc524","version_start_inclusive":true,"version_end":"8eb6dc76eeae5302c0d885906a0e469ef9630a59","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:3bd04fe7d807bbdcfe75b29ca82fae4e2d7dc524:8eb6dc76eeae5302c0d885906a0e469ef9630a59"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"3bd04fe7d807bbdcfe75b29ca82fae4e2d7dc524","version_start_inclusive":true,"version_end":"6ccbb613b42a1f1ba7bfd547a148f644a902a25c","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:3bd04fe7d807bbdcfe75b29ca82fae4e2d7dc524:6ccbb613b42a1f1ba7bfd547a148f644a902a25c"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.19","version_start_inclusive":true,"version_end":"6.19","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.19:6.19"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.19","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.19"},{"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/8eb6dc76eeae5302c0d885906a0e469ef9630a59","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/6ccbb613b42a1f1ba7bfd547a148f644a902a25c","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:40:40.694000Z","label":"CVE published","source":null}]}
