CVE-2026-20715: Improper input validation vulnerability

Improper input validation in some firmware for some Intel(R) Active Management Technology (Intel(R) AMT) and some Intel(R) Standard Manageability may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via network access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
