Summary
A vulnerability was found in MicroPython 1.22.2. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file py/objarray.c. The manipulation leads to use after free. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 1.23.0 is able to address this issue. The identifier of the patch is 4bed614e707c0644c06e117f848fa12605c711cd. It is recommended to upgrade the affected component. In micropython objarray component, when a bytes object is resized and copied into itself, it may reference memory that has already been freed.

La manipulaci\u00f3n conduce a un uso despu\u00e9s de la liberaci\u00f3n. El ataque se puede lanzar de forma remota. La complejidad de un ataque es bastante alta. La explotaci\u00f3n parece ser dif\u00edcil. La actualizaci\u00f3n a la versi\u00f3n 1.23.0 puede solucionar este problema. El identificador del parche es 4bed614e707c0644c06e117f848fa12605c711cd. Se recomienda actualizar el componente afectado. En el componente objarray de micropython, cuando se cambia el tama\u00f1o de un objeto de bytes y se copia en s\u00ed mismo, puede hacer referencia a la memoria que ya se ha liberado."
