A consistency issue was addressed with improved state handling. This issue is fixed in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5. An app may be able to gain root privileges.
The following code is for security research and authorized testing only.
python
#!/usr/bin/env python3
# PoC for CVE-2026-28919 (macOS Local Privilege Escalation)
# This is a conceptual demonstration of triggering the state consistency issue.
# Note: Actual exploit code requires detailed reverse engineering of the specific macOS state handling mechanism.
