Linux Kernel RTL8169 NIC Remote Denial of Service

The Linux Kernel is exposed to a remote denial of service issue in the NTL6269 driver. This issue occurs when a large packet is sent to a computer with NTL6269 NIC installed. Specifically, the driver permits frame sizes of up to 16383 bytes, but allocates only “skb” to “rx” rings of 1536 bytes.

Linux Kernel versions prior to 2.6.30 are affected.
