Executive Summary

This vulnerability is a memory leak in the Linux kernel's AppArmor security module. After a specific code change, the hname member of the aa_policy structure was incorrectly handled as a slab object and freed improperly, which caused a memory leak. The fix involves using the correct function, aa_policy_destroy(), to properly free this memory.

Impact Analysis

The memory leak could lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion on systems using AppArmor in the Linux kernel.
