This is exactly the case referred to in\nthe second comment in __iommu_device_set_domain() and just as stated\nthere if we can instead attach the blocking domain the UAF is prevented\nas this can handle the already removed device. Implement the blocking\ndomain to use this handling.

Este fallo ocurre porque durante la desconexi\u00f3n en caliente __iommu_group_set_domain_nofail() la conexi\u00f3n del dominio predeterminado falla cuando la plataforma ya no reconoce el dispositivo porque ya se ha eliminado y terminamos con un puntero de dominio NULL y UAF. Este es exactamente el caso al que se hace referencia en el segundo comentario en __iommu_device_set_domain() y tal como se indica all\u00ed, si en su lugar podemos conectar el dominio de bloqueo, se evita el UAF ya que puede gestionar el dispositivo ya eliminado. Implemente el dominio de bloqueo para usar esta gesti\u00f3n. Con este cambio, el fallo se corrige, pero a\u00fan encontramos una advertencia al intentar cambiar la propiedad de DMA en un dispositivo bloqueado."}], "lastModified": "2025-02-10T18:15:28.727", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "21434379-192D-472F-9B54-D45E3650E893", "versionEndExcluding": "6.11.11", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D8882B1B-2ABC-4838-AC1D-DBDBB5764776", "versionEndExcluding": "6.12.2", "versionStartIncluding": "6.12"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
