Summary

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.

Exploit prediction

0.54% chance of exploitation in the next 30 days, higher than 45% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
