CVE-2026-0827
Published: 15 April 2026
Summary
CVE-2026-0827 is a medium-severity Link Following (CWE-59) vulnerability in Lenovo Diagnostics (inferred from references). Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 5.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-6 (Least Privilege) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-0827 is a vulnerability discovered during an internal security assessment in Lenovo Diagnostics and the HardwareScanAddin used in Lenovo Vantage. The issue allows a local authenticated user to perform an arbitrary file write with elevated privileges during installation or when using the hardware scan feature. It carries a CVSS v3.1 base score of 7.1 (High), with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H, and is classified under CWE-59.
A local authenticated user with low privileges can exploit the vulnerability through low-complexity actions requiring no user interaction. Exploitation enables arbitrary file writes using elevated privileges, resulting in high impacts to system integrity and availability, while confidentiality remains unaffected.
