In this case, reipl_type_init()selects IPL_TYPE_UNKNOWN, and reipl_block_actual remains NULL.\nkdump passes the re-IPL parameter block to the dump kernel throughos_info. Before commit 3b9678472bab (\"s390/ipl: correct kdump reiplblock checksum calculation\"), the os_info entry was added only forIPL types which initialized reipl_block_actual. That commit moved theos_info update to machine_crash_shutdown(), making it unconditional. Asa result, set_os_info_reipl_block() dereferences reipl_block_actual forIPL_TYPE_UNKNOWN. This may happen to work by chance when address zerocontains readable lowcore data and the resulting empty os_info entry isignored by the dump kernel.\nSkip the os_info update when no re-IPL parameter block is available.Kdump then collect the dump and reboot without setting re-IPL parameterblock.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98400https://git.kernel.org/stable/c/030e88812435fc5d6aa42eee41fa77b5ea620327https://git.kernel.org/stable/c/92d0829eae257544b6b0faccb6e7079c45e22d48https://git.kernel.org/stable/c/50f9c40768e84f30d374235b3ee3850a94d9ac29https://git.kernel.org/stable/c/b6bf82bc5e00afaf836f8bb9a676bffc182a6bbdhttps://git.kernel.org/stable/c/7f918871112e8e7c581e99eb8e545af4e59c8367#kernel #Linux#CVE_2026_98400#bot", "url": "https://infosec.exchange/users/cve/statuses/117440690815877534"}, {"timestamp": "2026-10-16T01:05:20Z", "date_only": false, "value": "2026-10-16T01:05:20.000Z", "kind": "other", "label": "Advisory revision", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98400", "record": "MSRC_CVE-2026-98400", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2026-10-16T01:05:20Z", "date_only": false, "value": "2026-10-16T01:05:20.000Z", "kind": "milestone", "label": "Published", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98400", "record": "MSRC_CVE-2026-98400", "field": "document.tracking.initial_release_date"}, {"timestamp": "2026-10-16T01:05:20Z", "date_only": false, "value": "2026-10-16T01:05:20.000Z", "kind": "other", "label": "Updated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98400", "record": "MSRC_CVE-2026-98400", "field": "document.tracking.current_release_date"}, {"timestamp": "2026-10-16T06:05:38.849Z", "date_only": false, "value": "2026-10-16T06:05:38.84912Z", "kind": "milestone", "label": "Published", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98400", "record": "BELL-CVE-2026-98400", "field": "published"}, {"timestamp": "2026-10-16T06:42:47.413Z", "date_only": false, "value": "2026-10-16T06:42:47.413493Z", "kind": "other", "label": "Updated", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98400", "record": "BELL-CVE-2026-98400", "field": "modified"}, {"timestamp": "2026-10-16T07:00:53.913Z", "date_only": false, "value": "2026-10-16T07:00:53.913Z", "kind": "other", "label": "Document generated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-98400", "record": "MSRC_CVE-2026-98400", "field": "document.tracking.generator.date"}]}
