Local privilege escalation via hard-coded cryptographic key
Published Aug 13, 2026 · Updated Aug 13, 2026
Use of a hard-coded cryptographic key in Lenovo Accessories and Display Manager before 1.0.9 allows local users to execute elevated code. Lenovo identifies CWE-321 but does not disclose the key, its storage locus, the cryptographic operation that uses it, or how unprivileged input reaches that operation. A locally authenticated Windows user with low privileges can exploit the flaw without user interaction, gaining arbitrary code execution with elevated privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
