Descriptions

In the Linux kernel, the following vulnerability has been resolved:

net: bcmasp: fix memory leak when bringing down interface

When bringing down the TX rings we flush the rings but forget to
reclaimed the flushed packets. This leads to a memory leak since we
do not free the dma mapped buffers. This also leads to tx control
block corruption when bringing down the interface for power
management.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: bcmasp: corrige la pérdida de memoria al desactivar la interfaz. Al desactivar los anillos TX, los limpiamos pero nos olvidamos de recuperar los paquetes eliminados. Esto provoca una pérdida de memoria ya que no liberamos los búfers asignados por dma. Esto también conduce a la corrupción del bloque de control de transmisión al desactivar la interfaz para la administración de energía.
