Background
The Kernel is a fundamental component of the Linux operating system that manages core system functions and provides an interface between hardware and software. It is responsible for tasks such as process management, memory management, and device drivers. The ipack module in the Kernel is used for handling IP over Octal Data Link Control (IPoDL) packets. This vulnerability in the ipoctal component of ipack allows for a stack information leak.
Vulnerability Detail
The ipoctal component in the ipack module of the Kernel suffers from a stack information leak vulnerability. This vulnerability allows an attacker to obtain sensitive information from the stack memory, potentially leading to further exploitation. The vulnerability was introduced in version v3.5 of the Kernel and has been fixed in version v5.14.10. The impact and attack plausibility of this vulnerability have not been proven yet.
How To Fix
