It has been classified as problematic. Affected is some unknown functionality. The manipulation with an unknown input leads to a authentication bypass vulnerability. CWE is classifying the issue as CWE-305. The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Dell Client Platform BIOS contains an Authentication Bypass by Primary Weakness vulnerability. An unauthenticated attacker with physical access could potentially exploit this vulnerability, leading to Information Disclosure.

The advisory is available at dell.com. This vulnerability is traded as CVE-2026-35159 since 04/01/2026. The exploitability is told to be difficult. Local access is required to approach this attack. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/03/2026).
