What is CVE-2004-0114?

The shmat system call in the System V Shared Memory interface for FreeBSD, NetBSD, and OpenBSD has a flaw in reference count management. When the vm_map_find function fails, it fails to decrement the reference count of a shared memory segment. This oversight allows local users to potentially access kernel memory regions, leading to unauthorized read or write operations and enabling privilege escalation within the system.
