| Feature | Residual Risk | Status March 2026 |
|---|---|---|
| Apple Intelligence | Prompt injection | Locally mitigated |
| Liquid Glass | GPU side-channel | Theoretical only |
| TestFlight | Malware distribution | Enhanced monitoring |
| CarPlay | Bluetooth MITM | Patched (iOS 26.2) |
Security Timeline
WWDC: iOS 26 announced. Early betas found to contain critical WebKit vulnerabilities.
Stable Release: 30 CVEs fixed. Private Compute Cloud integration deployed.
Major Patch: 2 actively exploited Zero-Day Kernel flaws patched.
Version 26.3.1: Current state. Maximum stability ahead of the iOS 26.5 cycle.
Apple Intelligence: AI Security
On-device processing minimizes data leakage, but Prompt Injection attacks attempt to bypass Siri's security instructions to perform unauthorized actions.
| Attack Vector | Description | Mitigation iOS 26.3+ |
|---|---|---|
| Prompt Injection | Malicious inputs via Siri/Mail | Contextual sandbox 🛡️ |
| Context Leak | Sensitive data sent to cloud | 95% on-device; E2E 🔐 |
| AI Phishing | Intelligent spam prioritization | ML filtering 26.2 |
Liquid Glass: The GPU Architecture
Despite the rumors, iLeakage (2023 Safari/CPU side-channel attack) does not directly affect the Liquid Glass GPU renderer. The architecture is protected by Pointer Authentication.
Recent Vulnerabilities
Key patches included in the iOS 26.3.1 branch:
| CVE | Impact | Official Status |
