In this case reipl_type_init() selectsIPL_TYPE_UNKNOWN and reipl_block_actual remains NULL. Nevertheless,dump_reipl_run() unconditionally dereferences it when preparing thelowcore fields. This may happen to work by chance when address zerocontains readable lowcore data. A zero IPL parameter block address isthen stored in lowcore, causing the stand-alone dumper to enter disabledwait after completing the dump.\nExplicitly store a zero IPL parameter block address and checksum when nore-IPL parameter block is available. This does not change the behavior:the stand-alone dumper completes the dump and halts, while valid re-IPLparameter blocks continue to be handled as before.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98399https://git.kernel.org/stable/c/41647864e62b28388ecccc23a82f0e0a091f4ef2https://git.kernel.org/stable/c/aed56fa3108b7095e6a048e134981506c056a6cbhttps://git.kernel.org/stable/c/8d7988e8116c3d29d9e02ca9d37ee84577643f2dhttps://git.kernel.org/stable/c/280ff19853440d59e031cd8fe161e81305721262https://git.kernel.org/stable/c/37f61b71cbc0caefc01022a19ee56fc2510e2e6e#kernel #Linux#CVE_2026_98399#bot", "url": "https://infosec.exchange/users/cve/statuses/117440688168631368"}, {"timestamp": "2026-10-16T01:04:10Z", "date_only": false, "value": "2026-10-16T01:04:10.000Z", "kind": "other", "label": "Advisory revision", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98399", "record": "MSRC_CVE-2026-98399", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2026-10-16T01:04:10Z", "date_only": false, "value": "2026-10-16T01:04:10.000Z", "kind": "milestone", "label": "Published", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98399", "record": "MSRC_CVE-2026-98399", "field": "document.tracking.initial_release_date"}, {"timestamp": "2026-10-16T06:05:36.453Z", "date_only": false, "value": "2026-10-16T06:05:36.453383Z", "kind": "milestone", "label": "Published", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98399", "record": "BELL-CVE-2026-98399", "field": "published"}, {"timestamp": "2026-10-16T06:42:47.352Z", "date_only": false, "value": "2026-10-16T06:42:47.352363Z", "kind": "other", "label": "Updated", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98399", "record": "BELL-CVE-2026-98399", "field": "modified"}, {"timestamp": "2026-10-19T09:18:52.784Z", "date_only": false, "value": "2026-10-19T09:18:52.784Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-98399", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-19T09:18:52.784Z", "date_only": false, "value": "2026-10-19T09:18:52.784Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / Linux", "record": "CVE-2026-98399", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-19T10:18:44.700Z", "date_only": false, "value": "2026-10-19T10:18:44.700", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-98399", "record": "FKIE_CVE-2026-98399", "field": "lastModified"}, {"timestamp": "2026-10-20T14:21:49Z", "date_only": false, "value": "2026-10-20T14:21:49Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-98399", "record": "UBUNTU-CVE-2026-98399", "field": "modified"}, {"timestamp": "2026-10-21T18:42:07Z", "date_only": false, "value": "2026-10-21T18:42:07.000Z", "kind": "other", "label": "Advisory revision", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98399", "record": "MSRC_CVE-2026-98399", "field": "document.tracking.revision_history.1.date"}, {"timestamp": "2026-10-21T18:42:07Z", "date_only": false, "value": "2026-10-21T18:42:07.000Z", "kind": "other", "label": "Updated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98399", "record": "MSRC_CVE-2026-98399", "field": "document.tracking.current_release_date"}, {"timestamp": "2026-10-21T20:21:03.861Z", "date_only": false, "value": "2026-10-21T20:21:03.861Z", "kind": "other", "label": "Document generated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98399", "record": "MSRC_CVE-2026-98399", "field": "document.tracking.generator.date"}]}
