[Cómo] Para funciones que se ejecutan dentro de un contexto de DC o bloqueo de DC, podemos ajustar las llamadas directas a dm_execute_dmub_cmd/list con código que salga de las optimizaciones de energía inactivas y se vuelva a permitir una vez que hayamos terminado con el envío del comando en caso de éxito. Para envíos directos de DM, el DM deberá gestionar la secuencia de entrada/salida manualmente. No podemos invocar un comando DMCUB directamente dentro del asistente de ejecución de DM o podemos bloquearnos."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"6.7.3","matchCriteriaId":"F13B1885-F67C-4943-BD88-9B68D2C3FF83"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/303197775a97416b62d4da69280d0c120a20e009","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/8892780834ae294bc3697c7d0e056d7743900b39","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/303197775a97416b62d4da69280d0c120a20e009","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/8892780834ae294bc3697c7d0e056d7743900b39","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]}]}}]}
