Descriptions

The veth (aka virtual Ethernet) driver in the Linux kernel before 2.6.34 does not properly manage skbs during congestion, which allows remote attackers to cause a denial of service (system crash) by leveraging lack of skb consumption in conjunction with a double-free error.

El driver Veth (también conocido como Ethernet virtual) en el kernel Linux anterior a v2.6.34 no gestiona adecuadamente skbs durante la congestión, lo que permite a atacantes remotos provocar una denegación de servicio (caída del sistema), aprovechando la falta de consumo de skb junto con un error de doble liberación.
