CVE-2024-57892 is a use-after-free vulnerability in the ocfs2 filesystem implementation of the Linux kernel. It occurs when mounting ocfs2 and then remounting it as read-only, where a dangling pointer dqi_priv is accessed after being freed. This flaw can lead to high impact including confidentiality, integrity, and availability compromises. The issue was fixed by setting the dangling pointer to null after freeing and adding proper flag checks during quota operations.
