CVE-2021-33162

Status: AnalyzedHigh (8.4)—

Improper access control in some Intel(R) Ethernet Adapters and Intel(R) Ethernet Controller I225 Manageability firmware may allow an authenticated user to potentially enable escalation of privilege via local access.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
