Background

The igb package is a network driver for Intel Gigabit Ethernet Adapters. It is a part of the Linux Kernel ecosystem. The igb driver provides support for Intel 82575, 82576, 82580, I350, I210, and I211-based Gigabit Ethernet adapters. This driver allows communication between the operating system and the network adapter hardware.

Vulnerability Detail

The vulnerability in the igb package is a use-after-free error that occurs during a reset operation. This vulnerability was introduced in version v4.12 of the Linux Kernel and was fixed in version v4.19.199. The use-after-free error can lead to a situation where a program continues to use a memory region after it has been freed, potentially leading to a crash or arbitrary code execution. The impact and attack plausibility of this vulnerability have not been proven yet.
