CVE-2009-0876
CWE-59Published: March 12, 2009· Updated: Jun 16, 2026
6.9
CVSS v3.1
Official Description
Sun xVM VirtualBox 2.0.0, 2.0.2, 2.0.4, 2.0.6r39760, 2.1.0, 2.1.2, and 2.1.4r42893 on Linux allows local users to gain privileges via a hardlink attack, which preserves setuid/setgid bits on Linux, related to DT_RPATH:$ORIGIN.
Technical Analysis
CVE-2009-0876 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-2009-0876. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
