Linux Kernel Landlock Path List Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's Landlock sample, specifically within the path list management. The issue arises in the 'sandboxer.c' file, where the 'path_list' variable is allocated memory in the 'parse_path()' function but is never properly freed, leading to a potential memory leak.

Impact

Exploitation of this vulnerability could lead to a memory leak, where allocated memory is not released, potentially causing increased memory usage and degradation of system performance over time.
