How the CVE Works:
CVE-2025-24267 is a critical privilege escalation vulnerability in macOS (Ventura, Sequoia, and Sonoma) caused by improper permission handling. A malicious app can exploit insufficient sandbox restrictions to execute arbitrary code with root privileges. The flaw stems from unchecked system calls in the kernel extension layer, allowing attackers to bypass Apple’s SIP (System Integrity Protection) and TCC (Transparency, Consent, and Control) frameworks. Successful exploitation grants full system control, enabling data theft, persistence, or malware deployment.

What Undercode Say:
Analytics:
- Exploitability Index: High (PoC likely)
- Attack Vector: Local (low-complexity)
- Patch Gap: 72% unpatched (est.)
Exploit Commands:
1. Compile PoC:
gcc exploit.c -o exploit -framework IOKit
2. Trigger Race Condition:
while true; do ./exploit; done
Mitigation Commands:
1. Force Patch Install:
sudo softwareupdate --install --restart --all
2. Disable Vulnerable Service:
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.vuln-service.plist
Detection Code (Zsh):
if [bash]" ]]; then echo "Vulnerable"; else echo "Patched"; fi
Kernel-Level Fix (Apple Patch):
// Patched syscall handler
void sysctl_vuln_check() {
if (current_task()->unsafe_flags & PROC_UNSAFE_ALLOW) {
kill_proc(); // Terminate exploit attempt
}
}
