CVE-2025-38386

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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPICA: Negativa a evaluar un método si faltan argumentos. Como se informó en [1], una actualización de firmware de la plataforma que aumentó el número de parámetros del método y olvidó actualizar al menos uno de sus llamadores provocó 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 intérprete (no puede generar datos faltantes de la nada), se debe solucionar haciendo que ACPICA se niegue a evaluar un método si el llamante intenta pasarle menos argumentos de los esperados.
