Summary
The extension APIs in the kernel in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3 do not prevent the presence of addresses within an OSBundleMachOHeaders key in a response, which makes it easier for attackers to bypass the ASLR protection mechanism via a crafted app.
Exploit prediction
1.70% chance of exploitation in the next 30 days, higher than 77% of all scored CVEs (FIRST EPSS, 2026-11-09).

Fencer Intel 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.
