A race condition was addressed with improved state handling. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to gain root privileges.
The following code is for security research and authorized testing only.
python
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
// Simulated PoC for Race Condition Privilege Escalation
// This is a generic example demonstrating the concept of TOCTOU.
int main() {
const char* sensitive_file = "/etc/sudoers";
int fd;
// Step 1: Check permissions (Time of Check)
if (access(sensitive_file, W_OK) == 0) {
printf("[+] Write access granted. Attempting exploit...\n");
// Step 2: Time of Use (Race condition window)
// In a real scenario, a race occurs here where the resource is swapped or modified.
fd = open(sensitive_file, O_WRONLY);
if (fd >= 0) {
printf("[!] File opened successfully. Privilege escalation possible.\n");
close(fd);
} else {
printf("[-] Failed to open file.\n");
}
} else {
printf("[-] No write access.\n");
}
return 0;
