Background
The Kernel is a critical component of the Linux operating system that manages system resources and provides an interface for communication between hardware and software. It is responsible for tasks such as process management, memory management, and device drivers. The RSA algorithm is widely used for secure communication and data encryption. However, a memory leak vulnerability has been identified in the RSA implementation within the Kernel.
Vulnerability Detail
The vulnerability in the Kernel's RSA implementation leads to a memory leak. When performing RSA operations, memory is allocated but not properly freed, resulting in a continuous accumulation of memory over time. This can lead to resource exhaustion and potential denial-of-service attacks. The vulnerability was introduced in version 4.8 of the Kernel and has been fixed in version 5.18.15.
How To Fix
No fixed version is published for this vulnerability.
