Una operaci\u00f3n COPY o destroy concurrente puede competir con sev_migrate_from() y corromper la lista.\n\n- En sev_vm_destroy(), el propietario sigue activo y podr\u00eda recibir concurrentemente un KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM que hace que sev -> enc_context_owner cambie. En este caso la VM incorrecta recibe kvm_put_kvm().\n\nEl segundo problema requiere especial atenci\u00f3n porque el propietario podr\u00eda desaparecer por completo (aunque la ventana de competici\u00f3n es incre\u00edblemente peque\u00f1a) entre leerlo y bloquearlo. No hay, por lo tanto, manera de realizar las comprobaciones bajo el bloqueo del propietario sin poner la estructura kvm bajo SLAB_TYPESAFE_BY_RCU (lo que permitir\u00eda kvm_get_kvm_safe() bajo la secci\u00f3n cr\u00edtica de RCU).\n\nEs mucho m\u00e1s simple simplemente usar un bloqueo global, ya que las secciones cr\u00edticas son tan peque\u00f1as y el nuevo bloqueo es siempre un bloqueo hoja."}], "id": "CVE-2026-74607", "lastModified": "2026-10-16T20:17:45.763", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 2.0, "impactScore": 6.0, "source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-74607", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2026-10-16T19:02:09.291868Z", "version": "2.0.3"}}]}, "published": "2026-08-22T16:16:33.183", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/1d78d33275ef2a16c6d080910b291d0a97a0e613"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/28afde1edbd8b20058cbf4d75fb57876471ec334"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/328ab4fabe05af004d886659f8744076e320ddce"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/47976eaaf0a4eb46dade48b3246779090db9e3ec"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/7943ec3a6d0e7e0a2eb4943300bce089ac3e8c3e"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/d728baba0f20e49439fc7831bf3e4e7dee82161a"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Received"}
