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 vulnerability affects the igb driver in the Linux Kernel.
Vulnerability Detail
The vulnerability in the igb driver is a use-after-free error that occurs during a reset operation. A use-after-free vulnerability arises when a program continues to use a pointer after the memory it points to has been freed. In this case, during a reset, the igb driver does not properly handle the freeing of memory, leading to a use-after-free condition. An attacker could potentially exploit this vulnerability to execute arbitrary code or cause a denial-of-service condition.
How To Fix
No fixed version is published for this vulnerability.

FAQ
A use-after-free vulnerability occurs when a program continues to use a pointer after the memory it points to has been freed. This can lead to various security issues, including arbitrary code execution or denial-of-service.
An attacker could potentially exploit this vulnerability by crafting a malicious input that triggers the use-after-free condition. By exploiting this vulnerability, the attacker may be able to execute arbitrary code or cause a denial-of-service condition.
The impact of this vulnerability can vary depending on the attacker's capabilities and the target system. It could potentially lead to arbitrary code execution, allowing the attacker to take control of the affected system, or it could cause a denial-of-service condition, rendering the system inoperable.
Yes, this vulnerability has been fixed in the Linux Kernel version v4.19.199. It was addressed in commit d3ccb18ed5ac3283c7b31ecc685b499e580d5492.
