Descriptions

In the Linux kernel, the following vulnerability has been resolved: net: pds_core: Fix possible double free in error handling path When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release
calls kfree(padev) to free memory. We shouldn't call kfree(padev)
again in the error handling path. Fix this by cleaning up the redundant kfree() and putting
the error handling back to where the errors happened.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: pds_core: corrige posible doble liberación en la ruta de manejo de errores Cuando auxiliar_device_add() devuelve un error y luego llama a auxiliar_device_uninit(), la función de devolución de llamada pdsc_auxbus_dev_release llama a kfree(padev) para liberar memoria. No deberíamos volver a llamar a kfree(padev) en la ruta de manejo de errores. Solucione este problema limpiando el kfree() redundante y devolviendo el manejo de errores al lugar donde ocurrieron los errores.
