Descriptions
In the Linux kernel, the following vulnerability has been resolved:
iwlwifi: Fix memory leaks in error handling path
Should an error occur (invalid TLV len or memory allocation failure), the
memory already allocated in 'reduce_power_data' should be freed before
returning, otherwise it is leaking.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iwlwifi: soluciona pérdidas de memoria en la ruta de manejo de errores. Si ocurre un error (lengua TLV no válida o falla en la asignación de memoria), la memoria ya asignada en 'reduce_power_data' debe liberarse antes de regresar; de lo contrario, está goteando.
