Background
The Kernel is a crucial component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential functionalities and services to enable the proper functioning of the system. The vulnerability in question pertains to the ixgbe driver, which is responsible for managing Intel 10 Gigabit Ethernet adapters. This vulnerability specifically affects the suspend/resume functionality of the driver.
Vulnerability Detail
The vulnerability arises from an unbalanced device enable/disable operation during the suspend/resume process in the ixgbe driver. This imbalance can lead to inconsistent device states and potential system instability. An attacker with local access to the system could potentially exploit this vulnerability to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges. The vulnerability was introduced in version v5.9 of the Linux Kernel and has been fixed in version v5.10.32.
How To Fix
No fixed version is published for this vulnerability.
