Sin embargo, durante la suspensi\u00f3n del sistema con dispositivos USB conectados, varias solicitudes de apagado del panel UTMI resultan en una discrepancia en el recuento de referencia, lo que a su vez produce advertencias como: [ 237.762967] ADVERTENCIA: CPU: 10 PID: 1618 en tegra186_utmi_pad_power_down+0x160/0x170 [ 237.763103] Rastreo de llamadas: [ 237.763104] tegra186_utmi_pad_power_down+0x160/0x170 [ 237.763107] tegra186_utmi_phy_power_off+0x10/0x30 [ 237.763110] phy_power_off+0x48/0x100 [ 237.763113] tegra_xusb_enter_elpg+0x204/0x500 [ 237.763119] tegra_xusb_suspend+0x48/0x140 [ 237.763122] platform_pm_suspend+0x2c/0xb0 [ 237.763125] dpm_run_callback.isra.0+0x20/0xa0 [ 237.763127] __device_suspend+0x118/0x330 [ 237.763129] dpm_suspend+0x10c/0x1f0 [ 237.763130] dpm_suspend_start+0x88/0xb0 [ 237.763132] suspend_devices_and_enter+0x120/0x500 [ 237.763135] pm_suspend+0x1ec/0x270 La causa ra\u00edz se remonta a los cambios de apagado din\u00e1mico introducidos en el commit a30951d31b25 (\"xhci: tegra: USB2 pad power controls\"), donde el pad UTMI se apagaba sin verificar su estado actual. Este comportamiento desequilibrado provoc\u00f3 discrepancias en el recuento de referencias. Para rectificar este problema, este parche reemplaza el contador de referencia \u00fanico con una m\u00e1scara de bits, renombrada como utmi_pad_enabled. Cada bit en la m\u00e1scara corresponde a uno de los cuatro PHY USB2, lo que nos permite rastrear el estado de habilitaci\u00f3n de cada pad individualmente. Con este cambio: - El pad de polarizaci\u00f3n se enciende solo cuando la m\u00e1scara est\u00e1 despejada. - Cada pad UTMI se enciende o apaga seg\u00fan su bit correspondiente en la m\u00e1scara, lo que evita operaciones redundantes. El estado general de energ\u00eda del pad de polarizaci\u00f3n compartido se mantiene correctamente durante los ciclos de suspensi\u00f3n/reinicio. El mutex utilizado para evitar condiciones de ejecuci\u00f3n durante las operaciones de activaci\u00f3n/desactivaci\u00f3n del pad UTMI se ha trasladado de las funciones tegra186_utmi_bias_pad_power_on/off a las funciones principales tegra186_utmi_pad_power_on/down. Este cambio garantiza que no se produzcan condiciones de ejecuci\u00f3n al actualizar la m\u00e1scara de bits."}], "id": "CVE-2025-38010", "lastModified": "2026-11-05T21:18:02.337", "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-2025-38010", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-11-05T20:47:56.048425Z", "version": "2.0.3"}}]}, "published": "2025-06-18T10:15:32.283", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/1db527f0cb8f677adadd4e28e5bc77aaf5d4e4c9"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/628bec9ed68a2204184fc8230a2609075b08666e"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/b47158fb42959c417ff2662075c0d46fb783d5d1"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ba25131b3c1ceec303839b2462586d7673788197"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "NVD-CWE-Other"}], "source": "nvd@nist.gov", "type": "Primary"}]}
