CVE-2026-1636: CWE-427: Uncontrolled Search Path Element in Lenovo Service Bridge
A potential DLL hijacking vulnerability was reported in Lenovo Service Bridge that, under certain conditions, could allow a local authenticated user to execute code with elevated privileges.
AI Analysis
Technical Summary
This vulnerability in Lenovo Service Bridge is classified as CWE-427, indicating an uncontrolled search path element issue that can lead to DLL hijacking. A local authenticated user might exploit this to execute arbitrary code with elevated privileges. The CVSS 4.0 vector indicates local attack vector, low attack complexity, partial attack type, and privileges required as low, with user interaction needed. The vulnerability is published and assigned CVE-2026-1636 but currently lacks an official fix or patch from Lenovo.
Potential Impact
If exploited, this vulnerability could allow a local authenticated user to escalate privileges by executing malicious DLLs loaded by Lenovo Service Bridge. This could compromise system integrity and potentially lead to unauthorized actions performed with elevated rights. However, exploitation requires local access and user interaction, limiting remote attack feasibility. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the Lenovo vendor advisory for current remediation guidance. Until an official fix is available, restrict local user access to affected systems and monitor for suspicious activity related to DLL loading. Avoid running untrusted code or opening unverified files that could trigger DLL hijacking in Lenovo Service Bridge.
