CVE-2026-20709 Details
Description
Use of Default Cryptographic Key in the hardware for some Intel(R) Pentium(R) Processor Silver Series, Intel(R) Celeron(R) Processor J Series, Intel(R) Celeron(R) Processor N Series may allow an escalation of privilege. Hardware reverse engineer adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via physical access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
A vulnerability allowing privilege escalation has been identified in some Intel Pentium Processor Silver Series, Intel Celeron Processor J Series, and Intel Celeron Processor N Series. This issue arises from the use of a default cryptographic key in the hardware, which could be exploited by a hardware reverse engineer with privileged access. The attack, characterized by high complexity, may require physical access and special internal knowledge, but does not involve user interaction.
