Background
The Kernel package is a crucial component of the Linux operating system, responsible for managing the system's core functionality. It provides essential services, such as process management, memory management, and device drivers. The ipack module within the Kernel package is specifically related to handling input/output operations for octal-based IP addresses. This vulnerability in the ipoctal module allows for a module reference leak, potentially leading to resource exhaustion and system instability.
Vulnerability Detail
The vulnerability in the ipoctal module of the Kernel package arises from a module reference leak. This leak can occur when certain operations are performed on octal-based IP addresses, leading to the improper handling of module references. An attacker could potentially exploit this vulnerability to exhaust system resources, resulting in a denial-of-service condition or other forms of system instability. 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 v5.14.10 by commit 811178f296b16af30264def74c8d2179a72d5562. However, it was introduced in version v3.18 by commit 82a82340bab6c251e0705339f60763718eaa2a22.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is recommended to update the Kernel package to version v5.14.10 or later. This can be done by following the update process specific to the Linux distribution being used. It is crucial to ensure that the updated Kernel package is properly installed and configured to mitigate the vulnerability.
