Intel CPU Privilege Escalation Vulnerability, CVSS 4.7

CERT-Bund published a security advisory describing a privilege escalation vulnerability in Intel processors affecting the Pentium Silver Series, Celeron J Series, and Celeron N Series. The flaw allows local attackers with physical access to elevate privileges. The CVSS Base Score is 4.7 (medium) and Temporal Score is 4.3. Mitigation measures are available.

Organizations running these Intel processor families face potential exploitation if unpatched and if an attacker gains physical access. Immediate actions include identifying affected systems, applying firmware updates, and verifying that mitigations are properly deployed. Device manufacturers, technology companies, and government agencies should prioritize patching to prevent privilege escalation attacks.
