  3. CVE-2022-49817
In the Linux kernel, the following vulnerability has been resolved: net: mhi: Fix memory leak in mhi_net_dellink() MHI driver registers network device without setting the needs_free_netdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak. This patch calls free_netdev() to fix it since netdev_priv is used after unregister.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: mhi: Se corrige la pérdida de memoria en mhi_net_dellink(). El controlador MHI registra el dispositivo de red sin configurar el indicador needs_free_netdev y NO llama a free_netdev() al cancelar el registro del dispositivo de red, lo que provoca una pérdida de memoria. Este parche llama a free_netdev() para corregirla, ya que netdev_priv se utiliza después de cancelar el registro.
