Summary
CVE-2024-56749 is a vulnerability affecting the Linux kernel. This issue lies in the dlm (Distributed Lock Manager) module, specifically with the function dlm_recover_members(). In certain scenarios where this function fails, the references of the previous root_list are not dropped, leaving all rsbs (resource semaphores) alive during recovery. The potential for another recovery process to be triggered increases the likelihood of encountering this failure, potentially resulting in undesired system behavior.
