Memory Leak Vulnerability in Linux Kernel Affecting dm_integrity Component

CVE-2023-53604

What is CVE-2023-53604?

A memory leak vulnerability was identified in the Linux kernel's dm_integrity component. If the initialization of dm_integrity fails during the registration process, it results in an improper destruction of memory caches. Specifically, if the function dm_register_target() encounters an error, the journal_io_cache memory is not released, leading to potential memory leaks. This issue could impact system stability and performance by consuming system resources unnecessarily.
