Background

The Kernel is a critical component of the Linux operating system that provides core functionality and interfaces with hardware devices. It manages system resources, facilitates communication between software and hardware, and ensures the security and stability of the system. The ieee802154 module within the Kernel is responsible for supporting wireless communication using the IEEE 802.15.4 standard. The at86rf230 driver is specifically designed for the Atmel AT86RF230 radio transceiver. This vulnerability in the at86rf230 driver allows for the leakage of skb's (socket buffers), potentially leading to unauthorized access or information disclosure.

Vulnerability Detail

The vulnerability in the at86rf230 driver of the ieee802154 module allows for skb's to be leaked. This can occur due to improper handling of socket buffers, potentially leading to unauthorized access or information disclosure. Attackers may exploit this vulnerability to gain sensitive information or execute arbitrary code. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.10.102 by commit 0fd484644c68897c490a3307bfcc8bf767df5a43.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.10.102 or later. This can be done by applying the commit 0fd484644c68897c490a3307bfcc8bf767df5a43 to the Kernel source code. Detailed instructions on how to update the Kernel can be found in the official documentation or community resources.
