La devoluci\u00f3n de llamada puede eliminar un elemento kctl y esto puede provocar un punto muerto cuando el dispositivo estaba en estado suspendido. Es decir: * Un proceso espera el encendido en snd_power_ref_and_wait() en snd_ctl_info() o lectura/escritura() dentro de card->controls_rwsem. * Mientras tanto, el sistema se desconecta y el controlador intenta eliminar un kctl mediante snd_ctl_remove*(); intenta tomar card->controls_rwsem nuevamente, pero esto ya est\u00e1 bloqueado por lo anterior. Como el durmiente no se despierta, esto se bloquea. Una soluci\u00f3n f\u00e1cil es despertar a los durmientes antes de procesar las devoluciones de llamada de desconexi\u00f3n del controlador, pero justo despu\u00e9s de configurar la tarjeta->indicador de apagado. Entonces todos los durmientes abortar\u00e1n inmediatamente y el c\u00f3digo fluir\u00e1 nuevamente. B\u00e1sicamente, este parche mueve la llamada wait_event() en el momento adecuado. Mientras estamos en esto, solo para estar seguros, llame a wait_event_all() en lugar de wait_event(), aunque no usamos eventos exclusivos en esta cola por ahora."}], "id": "CVE-2024-38600", "lastModified": "2026-06-17T07:40:41.123", "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-2024-38600", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-09-10T17:13:24.578390Z", "version": "2.0.3"}}]}, "published": "2024-06-19T14:15:19.990", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/2f103287ef7960854808930499d1181bd0145d68"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6b55e879e7bd023a03888fc6c8339edf82f576f4"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/87988a534d8e12f2e6fc01fe63e6c1925dc5307c"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/88ce3fe255d58a93624b467af036dc3519f309c7"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/c2fb439f4f1425a961d20bec818fed2c2d9ef70a"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ff80185e7b7b547a0911fcfc8aefc61c3e8304d7"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/2f103287ef7960854808930499d1181bd0145d68"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6b55e879e7bd023a03888fc6c8339edf82f576f4"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/87988a534d8e12f2e6fc01fe63e6c1925dc5307c"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/88ce3fe255d58a93624b467af036dc3519f309c7"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/c2fb439f4f1425a961d20bec818fed2c2d9ef70a"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ff80185e7b7b547a0911fcfc8aefc61c3e8304d7"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-667"}], "source": "nvd@nist.gov", "type": "Primary"}]}

The callback may delete a kctl element, and this can lead to a\ndeadlock when the device was in the suspended state. Namely:\n* A process waits for the power up at snd_power_ref_and_wait() in\nsnd_ctl_info() or read/write() inside card->controls_rwsem.\n* The system gets disconnected meanwhile, and the driver tries to\ndelete a kctl via snd_ctl_remove*(); it tries to take\ncard->controls_rwsem again, but this is already locked by the\nabove. Since the sleeper isn't woken up, this deadlocks.\nAn easy fix is to wake up sleepers before processing the driver\ndisconnect callbacks but right after setting the card->shutdown flag.\nThen all sleepers will abort immediately, and the code flows again.\nSo, basically this patch moves the wait_event() call at the right\ntiming.
