Descriptions

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

net: mctp: take ownership of skb in mctp_local_output

Currently, mctp_local_output only takes ownership of skb on success, and
we may leak an skb if mctp_local_output fails in specific states; the
skb ownership isn't transferred until the actual output routing occurs.

Instead, make mctp_local_output free the skb on all error paths up to
the route action, so it always consumes the passed skb.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: mctp: toma posesión de skb en mctp_local_output Actualmente, mctp_local_output solo toma propiedad de skb en caso de éxito, y podemos filtrar un fallo skb si mctp_local_output en estados específicos; la propiedad del skb no se transfiere hasta que se produce el enrutamiento de salida real. En su lugar, haga que mctp_local_output libere el skb en todas las rutas de error hasta la acción de ruta, de modo que siempre consuma el skb pasado.
