CWE-264Published: July 25, 2006· Updated: Jun 16, 2026
2.1
CVSS v3.1
Official Description
heartbeat.c in heartbeat before 2.0.6 sets insecure permissions in a shmget call for shared memory, which allows local users to cause an unspecified denial of service via unknown vectors, possibly during a short time window on startup.
Technical Analysis
CVE-2006-3815 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-2006-3815. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
