Ahora que poweroff() desactiva correctamente los reguladores, al hacer esto dos veces se activa una ADVERTENCIA() en el n\u00facleo del regulador: desactivaciones desequilibradas para regulador ficticio ADVERTENCIA: CPU: 1 PID: 92 en drivers/regulator/core.c:2999 _regulator_disable .. Corrija lis3lv02d_i2c_suspend() para que no llame a poweroff() una segunda vez si ya est\u00e1 suspendido el tiempo de ejecuci\u00f3n y agregue una llamada a poweron() cuando sea necesario para que la reactivaci\u00f3n funcione. lis3lv02d_i2c_resume() tiene problemas similares, con el inconveniente adicional de que siempre enciende el dispositivo si el tiempo de ejecuci\u00f3n est\u00e1 suspendido, despu\u00e9s de lo cual la primera reanudaci\u00f3n del tiempo de ejecuci\u00f3n llamar\u00e1 a poweron() nuevamente, lo que provocar\u00e1 que el recuento habilitado para el regulador aumente en 1 cada suspender/reanudar. Estas llamadas desequilibradas regulator_enable() hacen que el regulador nunca se apague y activan la siguiente ADVERTENCIA() al desvincular el controlador: ADVERTENCIA: CPU: 1 PID: 1724 en drivers/regulator/core.c:2396 _regulator_put Solucione esto haciendo lis3lv02d_i2c_resume( ) refleja la nueva suspensi\u00f3n()."}], "id": "CVE-2024-35824", "lastModified": "2026-06-17T07:35:29.427", "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"}, {"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": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2024-35824", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-05-31T18:40:44.476426Z", "version": "2.0.3"}}]}, "published": "2024-05-17T14:15:18.033", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/4154e767354140db7804207117e7238fb337b0e7"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/997ca415384612c8df76d99d9a768e0b3f42b325"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ac3e0384073b2408d6cb0d972fee9fcc3776053d"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f6df761182fc953907b18aba5049fc2a044ecb45"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/4154e767354140db7804207117e7238fb337b0e7"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/997ca415384612c8df76d99d9a768e0b3f42b325"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ac3e0384073b2408d6cb0d972fee9fcc3776053d"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f6df761182fc953907b18aba5049fc2a044ecb45"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}], "source": "nvd@nist.gov", "type": "Primary"}]}
