CVE-2026-105051: CWE-348 Use of Less Trusted Source in Irdeto Denuvo Anti-Tamper
CVE-2026-105051 is a low-severity vulnerability in Irdeto's Denuvo Anti-Tamper product through version 2026-03-04. It allows bypass of a hypervisor presence check by intercepting CPUID instructions using specific drivers (SimpleSvm.sys on AMD and hyperkd.sys and hyperhv.dll on Intel). This flaw relates to the use of a less trusted source for security checks.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-105051 affects Denuvo Anti-Tamper versions up to and including 2026-03-04. It involves CWE-348, where a less trusted source is used in the hypervisor presence check mechanism. Attackers can bypass this check by intercepting CPUID instructions via certain drivers: SimpleSvm.sys on AMD platforms and hyperkd.sys and hyperhv.dll on Intel platforms. The CVSS v3.1 base score is 1.9, indicating low severity, with attack vector local, high attack complexity, and requiring high privileges. There is no confidentiality or availability impact, only a low integrity impact.
Potential Impact
The vulnerability allows an attacker with local high privileges to bypass the hypervisor presence check in Denuvo Anti-Tamper. This could potentially weaken anti-tamper protections by fooling the software about the presence of a hypervisor. However, the impact is limited to low integrity and does not affect confidentiality or availability. No known exploits are reported in the wild.
Mitigation Recommendations
No vendor advisory or patch information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should be aware that local attackers with high privileges could bypass hypervisor checks. No specific mitigation steps are documented.
