Por ejemplo, dos puertos Tipo-C comparten un irq. Despu\u00e9s de que el primer puerto termin\u00f3 tcpci_register_port(), puede activar la interrupci\u00f3n. Sin embargo, si la interrupci\u00f3n llega por casualidad, el segundo puerto termina devm_request_threaded_irq(), el controlador de interrupci\u00f3n del segundo puerto se ejecutar\u00e1 primero. Entonces, el problema anterior ocurre debido a que tcpci sigue siendo un puntero NULL en tcpci_irq() cuando se desreferencia a regmap. devm_request_threaded_irq() &lt;-- port1 irq viene deshabilitar_irq(client-&gt;irq); tcpci_register_port() Esto restaurar\u00e1 la l\u00f3gica al estado anterior a el commit (77e85107a771 \"usb: typec: tcpci: support edge irq\"). Sin embargo, mover tcpci_register_port() antes crea un problema cuando se usa el irq de borde porque tcpci_init() se llamar\u00e1 antes que devm_request_threaded_irq(). tcpci_init() escribe ALERT_MASK en el hardware para indicarle que comience a generar interrupciones, pero a\u00fan no estamos listos para lidiar con ellas, entonces los eventos ALERT pueden perderse y la l\u00ednea ALERT no se recuperar\u00e1 al nivel alto para siempre. Para evitar el problema, esto tambi\u00e9n establecer\u00e1 el registro ALERT_MASK despu\u00e9s del retorno de devm_request_threaded_irq()."}], "id": "CVE-2024-57914", "lastModified": "2025-01-31T15:19:21.703", "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": "2025-01-19T12:15:25.573", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/8586d6ea623e48b2bd38304bbc52b0b8228816ff"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/862a9c0f68487fd6ced15622d9cdcec48f8b5aaa"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-476"}], "source": "nvd@nist.gov", "type": "Primary"}]}
