If userspace then freezes reshape and\nwrites md/suspend_lo or md/suspend_hi, mddev_suspend() kills active_io\nand waits for all in-flight IO to drain.\n\nThis can deadlock: the IO needs reshape progress to continue, but the\nreshape thread is already frozen, so the active_io reference is never\ndropped and suspend never completes.\n\nraid5_prepare_suspend() already wakes wait_for_reshape for dm-raid. Do\nthe same for normal md suspend when reshape is already interrupted, so\nwaiting raid456 IO can abort, drop its reference, and let suspend\nfinish.\n\nThe mdadm test tests/25raid456-reshape-deadlock reproduces the hang.","published_at":"2026-06-24T16:30:52.609000Z","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/8b6a72420821e6da2cab6a69d5233500d2698b93","https://git.kernel.org/stable/c/ff6b93410192b812d73cc54062529715b2dc849f","https://git.kernel.org/stable/c/8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0","https://git.kernel.org/stable/c/cf86bb53b9c92354904a328e947a05ffbfdd1840"],"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":"2026-06-28T23:30:50.753831Z"},"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":"714d20150ed85811193ae07a494d91f9927c590f","version_start_inclusive":true,"version_end":"8b6a72420821e6da2cab6a69d5233500d2698b93","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:714d20150ed85811193ae07a494d91f9927c590f:8b6a72420821e6da2cab6a69d5233500d2698b93"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"714d20150ed85811193ae07a494d91f9927c590f","version_start_inclusive":true,"version_end":"ff6b93410192b812d73cc54062529715b2dc849f","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:714d20150ed85811193ae07a494d91f9927c590f:ff6b93410192b812d73cc54062529715b2dc849f"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"714d20150ed85811193ae07a494d91f9927c590f","version_start_inclusive":true,"version_end":"8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:714d20150ed85811193ae07a494d91f9927c590f:8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"714d20150ed85811193ae07a494d91f9927c590f","version_start_inclusive":true,"version_end":"cf86bb53b9c92354904a328e947a05ffbfdd1840","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:714d20150ed85811193ae07a494d91f9927c590f:cf86bb53b9c92354904a328e947a05ffbfdd1840"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.7","version_start_inclusive":true,"version_end":"6.7","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.7:6.7"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.7","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.7"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.12.91","version_start_inclusive":true,"version_end":"6.12.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.12.91:6.12.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.18.33","version_start_inclusive":true,"version_end":"6.18.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.18.33:6.18.*"},{"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/8b6a72420821e6da2cab6a69d5233500d2698b93","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/ff6b93410192b812d73cc54062529715b2dc849f","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/cf86bb53b9c92354904a328e947a05ffbfdd1840","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-24T16:30:52.609000Z","label":"CVE published","source":null}]}
