Detailsinfo

A vulnerability was found in Intel Pentium Processor Silver, Celeron Processor J and Celeron Processor N (version now known) and classified as problematic. This issue affects some unknown processing. The manipulation with an unknown input leads to a default key vulnerability. Using CWE to declare the problem leads to CWE-1394. The product uses a default cryptographic key for potentially critical functionality. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at intel.com. The identification of this vulnerability is CVE-2026-20709 since 01/29/2026. The exploitation is known to be difficult. An attack has to be approached locally. Additional levels of successful authentication are needed for exploitation. Neither technical details nor an exploit are publicly available.
