CVE-2026-20709
Description
A flaw was found in some Intel Pentium Processor Silver Series, Intel Celeron Processor J Series, and Intel Celeron Processor N Series. This vulnerability arises from the use of a default cryptographic key in the hardware. A sophisticated attacker with physical access and privileged user access could exploit this to achieve an escalation of privilege, potentially compromising the system's confidentiality and integrity.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
