Descriptions

The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload (GRO) is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service (system crash) via crafted network traffic.

La función skb_gro_header_slow en includelinuxnetdevice.h en kernel de Linux anteriores a v2.6.39.4, cuando está activada la opción Generic Receive Offload (GRO), reinicia ciertos campos en situaciones incorrectas, lo que permite producir una denegación de servicio (caída del sistema) mediante una tráfico de red manipulado.
