Esto lleva a UAF porque al poner los relojes se acceder\u00e1 a los relojes en los datos del controlador pmif, que ya est\u00e1n liberados junto con spmi_controller. Esto se puede reproducir habilitando DEBUG_TEST_DRIVER_REMOVE y compilando el kernel con KASAN. Solucione el problema de UAF utilizando clk_bulk_get() no administrado y poniendo los relojes antes de liberar spmi_controller."}], "id": "CVE-2023-52584", "lastModified": "2026-06-17T06:43:05.047", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 3.8, "baseSeverity": "LOW", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "privilegesRequired": "HIGH", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N", "version": "3.1"}, "exploitabilityScore": 1.2, "impactScore": 2.5, "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2023-52584", "options": [{"exploitation": "poc"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2024-03-06T15:36:25.441828Z", "version": "2.0.3"}}]}, "published": "2024-03-06T07:15:07.227", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/521f28eedd6b14228c46e3b81e3bf9b90c2818d8"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9a3881b1f07db1bb55cb0108e6f05cfd027eaf2e"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/e821d50ab5b956ed0effa49faaf29912fd4106d9"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f8dcafcb54632536684336161da8bdd52120f95e"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/521f28eedd6b14228c46e3b81e3bf9b90c2818d8"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9a3881b1f07db1bb55cb0108e6f05cfd027eaf2e"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/e821d50ab5b956ed0effa49faaf29912fd4106d9"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f8dcafcb54632536684336161da8bdd52120f95e"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-416"}], "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}]}
