El propio controlador de interrupciones garantiza que el disparador siempre ser\u00e1 v\u00e1lido entre request_irq() y free_irq(), pero los mecanismos de prueba de bucle invertido para invocar la funci\u00f3n del controlador deben probar el disparador. Las rutas de activaci\u00f3n y configuraci\u00f3n de ioctl utilizan igate y, por lo tanto, son mutuamente excluyentes. El controlador vfio-fsl-mc no utiliza irqfds ni admite ning\u00fan tipo de operaci\u00f3n de enmascaramiento; por lo tanto, a diferencia de vfio-pci y vfio-platform, el flujo puede permanecer esencialmente sin cambios."}], "id": "CVE-2024-26814", "lastModified": "2025-03-27T21:36:57.227", "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"}]}, "published": "2024-04-05T09:15:09.393", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/083e750c9f5f4c3bf61161330fb84d7c8e8bb417"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/250219c6a556f8c69c5910fca05a59037e24147d"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6ec0d88166dac43f29e96801c0927d514f17add9"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7447d911af699a15f8d050dfcb7c680a86f87012"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/a563fc18583ca4f42e2fdd0c70c7c618288e7ede"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/de87511fb0404d23b6da5f4660383b6ed095e28d"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ee0bd4ad780dfbb60355b99f25063357ab488267"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/083e750c9f5f4c3bf61161330fb84d7c8e8bb417"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/250219c6a556f8c69c5910fca05a59037e24147d"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6ec0d88166dac43f29e96801c0927d514f17add9"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7447d911af699a15f8d050dfcb7c680a86f87012"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/a563fc18583ca4f42e2fdd0c70c7c618288e7ede"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/de87511fb0404d23b6da5f4660383b6ed095e28d"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ee0bd4ad780dfbb60355b99f25063357ab488267"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Mailing List"], "url": "https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-476"}], "source": "nvd@nist.gov", "type": "Primary"}]}
