Memory Leak Vulnerability in Linux Kernel's AppArmor

CVE-2024-56741

Summary

A memory leak vulnerability exists within the Linux kernel's AppArmor functionality, specifically in the aa_unpack_strdup() function. The issue arises from the use of kmemdup() to allocate a string, which is not properly freed, leading to memory leaks during execution. As a result, this oversight can cause unreferenced memory objects to accumulate, potentially impacting system performance and stability. Effective measures to address this vulnerability involve ensuring that allocated memory is properly released after use. System administrators and developers are encouraged to monitor and apply relevant kernel updates to mitigate any associated risks.
