CWE-20Published: November 19, 2019· Updated: Jun 16, 2026
7.8
CVSS v3.1
Official Description
ktsuss versions 1.4 and prior spawns the GTK interface to run as root. This can allow a local attacker to escalate privileges to root and use the "GTK_MODULES" environment variable to possibly execute arbitrary code.
Technical Analysis
CVE-2011-2922 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
