XFRM_MSG_MIGRATE / SADB_X_MIGRATE.\n\nXFRM_MSG_MIGRATE arrives on a per-netns NETLINK_XFRM socket, and the\nrest of the xfrm/af_key netlink path was made netns-aware in 2008.\nThe other 14 multicast paths in xfrm_user.c route their event using\nxs_net(x), xp_net(xp) or sock_net(skb->sk); only the migrate path\nwas missed.\n\nTwo consequences of the init_net hardcoding:\n\n 1. The notification (selector, old/new endpoint addresses, and the\n km_address) is delivered to listeners on init_net's\n XFRMNLGRP_MIGRATE / pfkey BROADCAST_ALL groups rather than on\n the issuing netns. An IKE daemon running in init_net therefore\n receives migration notifications originating from any other\n netns on the host.\n\n 2. An IKE daemon running inside a non-init netns and subscribed\n to its own XFRMNLGRP_MIGRATE / pfkey groups never receives the\n notification of its own migration. IKEv2 MOBIKE / address-update\n handling inside a netns is silently broken.\n\nThread struct net through km_migrate() and the xfrm_mgr.migrate\nfunction pointer, drop the &init_net override in xfrm_send_migrate()\nand pfkey_send_migrate(), and pass the caller's net (already in\nscope in xfrm_migrate() via sock_net(skb->sk)) all the way down.\nstruct xfrm_mgr is in-tree only and not exported as a stable API,\nso the function-pointer signature change is internal.\n\npfkey_broadcast() is already netns-aware via net_generic(net,\npfkey_net_id) since the pernet conversion. The five other\npfkey_broadcast() callers in af_key.c already pass xs_net(x),\nsock_net(sk) or a per-netns net, so this only removes the\n&init_net outlier."}], "id": "CVE-2026-63914", "lastModified": "2026-10-30T17:47:30.490", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "LOW", "baseScore": 7.3, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L", "version": "3.1"}, "exploitabilityScore": 2.0, "impactScore": 4.7, "source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-63914", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-10-16T15:33:13.785456Z", "version": "2.0.3"}}]}, "published": "2026-07-19T16:17:09.373", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/00f2c451e57df50b1151d9b2254878f106b7c892"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/26ce8dbf2e23fe4fcc3351d19ef6d3fb703ed126"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/448bb92ca101dde8a6e88b4dc824044b4e341604"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6df8157547347b5257bf640a0ae3dfc4411e06cd"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7e2a4f7ca0952820731ef7bdadfc9a9e9d3571b4"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/a306cf2ac8849c487791369fad6f216399d000f6"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/bafc7d0774b9bf52909c70ed990bc5ccf7ec4bad"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/fe463798343382c8fe9416a95959f005a3c30aa5"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-668"}], "source": "nvd@nist.gov", "type": "Primary"}, {"description": [{"lang": "en", "value": "CWE-862"}], "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}]}
