  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nnet: usb: smsc75xx: Limit packet length to skb->len\nPacket length retrieved from skb data may be larger than\nthe actual socket buffer length (up to 9026 bytes). In such\ncase the cloned skb passed up the network stack will leak\nkernel memory contents." ],
  "statement" : "The vulnerability in SMSC LAN75XX based USB 2.0 gigabit ethernet devices driver arises because the driver fails to properly validate packet length fields when receiving network frames. Specifically, the code used size values that could exceed the actual skb->len, leading to a situation where kernel memory beyond the buffer is copied into the outgoing skb. If the driver is active, a remote attacker on the same network can send oversized Ethernet frames to trigger this bug, resulting in leakage of uninitialized kernel memory (CIA: HNN, Confidentiality: High).",
