  3. CVE-2022-48720
In the Linux kernel, the following vulnerability has been resolved: net: macsec: Fix offload support for NETDEV_UNREGISTER event Current macsec netdev notify handler handles NETDEV_UNREGISTER event by releasing relevant SW resources only, this causes resources leak in case of macsec HW offload, as the underlay driver was not notified to clean it's macsec offload resources. Fix by calling the underlay driver to clean it's relevant resources by moving offload handling from macsec_dellink() to macsec_common_dellink() when handling NETDEV_UNREGISTER event.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: macsec: se corrigió el soporte de descarga para el evento NETDEV_UNREGISTER. El controlador de notificación netdev de macsec actual maneja el evento NETDEV_UNREGISTER liberando solo recursos SW relevantes, lo que provoca una pérdida de recursos en caso de descarga de HW de macsec, ya que No se notificó al controlador subyacente que limpiara sus recursos de descarga de macsec. Para solucionarlo, llame al controlador subyacente para limpiar sus recursos relevantes moviendo el manejo de descarga de macsec_dellink() a macsec_common_dellink() cuando se maneja el evento NETDEV_UNREGISTER.
