In the next raid5d loop iteration,\nrelease_stripe_list() drains the stripe onto handle_list (since\nSTRIPE_HANDLE is set by the original IO), but retry_aligned_read()\nruns before handle_active_stripes() and removes the stripe from\nhandle_list via find_get_stripe() -> list_del_init(). This prevents\nhandle_stripe() from ever processing the stripe to resolve the\noverlap, causing an infinite loop and soft lockup.\n\nFix this by using __release_stripe() with temp_inactive_list instead\nof raid5_release_stripe() in the failure path, so the stripe does not\ngo through the released_stripes llist. This allows raid5d to break out\nof its loop, and the overlap will be resolved when the stripe is\neventually processed by handle_stripe()."}], "lastModified": "2026-06-17T10:52:58.210", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EA6C5294-BBD9-44A8-9AEE-C1786E1839D6", "versionEndExcluding": "5.10.258", "versionStartIncluding": "3.12"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "919C10A9-7951-4A74-BADD-C135A0A8D8B4", "versionEndExcluding": "5.15.209", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "92385813-D91D-480D-83A1-F423D2CBB2BA", "versionEndExcluding": "6.1.175", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A1A92866-F406-43B5-B2D1-CFC274753E9D", "versionEndExcluding": "6.6.140", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "55DA1C62-9991-451E-B8A8-E0004E00F789", "versionEndExcluding": "6.12.86", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A10AC84F-C058-47D5-85B4-E6E51A613B74", "versionEndExcluding": "6.18.27", "versionStartIncluding": "6.13"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CDB78D6D-22C3-4154-B0D0-94AF1CE5C2E3", "versionEndExcluding": "7.0.4", "versionStartIncluding": "6.19"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
