NVD-CWE-OtherPublished: March 3, 2004· Updated: Jun 16, 2026
Official Description
The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.
Technical Analysis
CVE-2004-0114 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2004-0114. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
