Background
The Kernel is a critical component of the Linux operating system that manages communication between hardware and software. It provides essential functions and services to enable the proper functioning of the system. This vulnerability specifically affects the Kernel version prior to v5.15.56. The vulnerability arises from a memory leak issue in the 'init_desc' function of the 'evm' module.
Vulnerability Detail
The 'evm' module in the Kernel is responsible for handling Extended Verification Module (EVM) operations. The 'init_desc' function within this module had a memory leak issue, which could lead to the exhaustion of system resources over time. An attacker could potentially exploit this vulnerability to cause a denial-of-service (DoS) condition or impact system stability. The vulnerability has been fixed in Kernel version v5.15.56 by commit fb593531571c93cc1595a0ad10474de2a72d1ec7.
