Pero ese c\u00f3digo no requiere manejar fallos de asignaci\u00f3n de interrupciones. Si no se puede asignar la interrupci\u00f3n, la entrega del temporizador fallo y entra en p\u00e1nico debido a eso o vuelve al modo heredado. Solucione esto eliminando el contenedor de p\u00e1nico alrededor de __add_pin_to_irq_node() y haciendo que mp_irqdomain_alloc() sea consciente de la condici\u00f3n de fallo y la maneje como cualquier otra fallo en esta funci\u00f3n de manera elegante."}], "id": "CVE-2024-49927", "lastModified": "2026-06-17T08:00:45.030", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2024-49927", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-10-22T13:39:34.506279Z", "version": "2.0.3"}}]}, "published": "2024-10-21T18:15:14.737", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/077e1b7cd521163ded545987bbbd389519aeed71"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/649a5c2ffae797ce792023a70e84c7fe4b6fb8e0"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/830802a0fea8fb39d3dc9fb7d6b5581e1343eb1f"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/e479cb835feeb2abff97f25766e23b96a6eabe28"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ec862cd843faa6f0e84a7a07362f2786446bf697"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f17efbeb2922327ea01a9efa8829fea9a30e547d"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}], "source": "nvd@nist.gov", "type": "Primary"}]}
