Summary
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Refuse to evaluate a method if arguments are missing As reported in [1], a platform firmware update that increased the number of method parameters and forgot to update a least one of its callers, caused ACPICA to crash due to use-after-free. Since this a result of a clear AML issue that arguably cannot be fixed up by the interpreter (it cannot produce missing data out of thin air), address it by making ACPICA refuse to evaluate a method if the caller attempts to pass fewer arguments than expected to it.

Como se inform\u00f3 en [1], una actualizaci\u00f3n de firmware de la plataforma que aument\u00f3 el n\u00famero de par\u00e1metros del m\u00e9todo y olvid\u00f3 actualizar al menos uno de sus llamadores provoc\u00f3 el bloqueo de ACPICA debido al use-after-free. Dado que esto se debe a un claro problema de AML que posiblemente no pueda ser solucionado por el int\u00e9rprete (no puede generar datos faltantes de la nada), se debe solucionar haciendo que ACPICA se niegue a evaluar un m\u00e9todo si el llamante intenta pasarle menos argumentos de los esperados."
