Background
The Linux kernel is the core component of many operating systems, responsible for managing hardware resources and providing essential services to software applications. It is known for its stability, performance, and security features. However, vulnerabilities can arise, impacting the kernel's functionality and the overall system's security. CVE-2024-57841 is a specific vulnerability that affects the Linux kernel in Debian versions 12 and 13, leading to potential memory leaks.
Vulnerability Detail
CVE-2024-57841 is a memory leak vulnerability found in the tcp_conn_request() function of the Linux kernel. The issue occurs when the inet_csk_reqsk_queue_hash_add() function returns false, causing tcp_conn_request() to exit without freeing the allocated destination (dst) memory. This unreferenced memory can lead to increased memory usage over time, potentially affecting system performance and stability. The vulnerability was identified through kmemleak, which showed an unreferenced object in memory, indicating that the allocated memory was not properly released.
