CVE-2017-6975

Status: ModifiedMedium (6.8)—

Wi-Fi in Apple iOS before 10.3.1 does not prevent CVE-2017-6956 stack buffer overflow exploitation via a crafted access point. NOTE: because an operating system could potentially isolate itself from CVE-2017-6956 exploitation without patching Broadcom firmware functions, there is a separate CVE ID for the operating-system behavior.

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).
