CVE-2007-5043
CWE-20Published: September 24, 2007· Updated: Jun 16, 2026
4.4
CVSS v3.1
Official Description
Kaspersky Internet Security 7.0.0.125 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to (1) cause a denial of service (crash) and possibly gain privileges via the NtCreateSection kernel SSDT hook or (2) cause a denial of service (avp.exe service outage) via the NtLoadDriver kernel SSDT hook. NOTE: this issue may partially overlap CVE-2006-3074.
Technical Analysis
CVE-2007-5043 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.
