    An attacker would need to convince the user to install and run a malicious app. Once the app is launched, it can exploit the vulnerability to escalate its privileges to root level. With root privileges, the app can then perform actions that are typically restricted, such as modifying system files, installing software, and accessing sensitive data.

    Conceptual Example Code

    Conceptually, an exploit might look like this:

    #!/bin/bash
# This is a conceptual demonstration of an exploit, not actual exploit code
echo "Installing malicious app"
# The malicious app is installed
install_malicious_app
echo "Launching app"
# The app is launched
launch_app
echo "Exploiting vulnerability to gain root privileges"
# The app utilizes the vulnerability to escalate its privileges
exploit_vulnerability
echo "Malicious actions performed with root privileges"
# The app performs actions that would typically be restricted
perform_malicious_actions

    In the real world, the exploit would likely involve more complex code and obfuscation techniques to avoid detection by security software.

    Mitigation

    The vendor has addressed this issue in macOS Sequoia 15.6, therefore it is strongly recommended to update to the latest version of the operating system. If updating is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. It’s also important to follow best security practices such as avoiding the installation of apps from unknown sources and regularly backing up important data.

    #include <stdio.h>
#include <stdlib.h>
int main() {
// Initialization of a pointer to a heap memory space
int *ptr = malloc(10 * sizeof(int));
// Processing of a maliciously crafted file leading to heap corruption
if (ptr == NULL) {
printf("Memory not allocated.\n");
exit(0);
}
else {
// Memory has been successfully allocated
printf("Memory successfully allocated using malloc.\n");
// Get the element of the array
for (int i = 0; i < 10; ++i) {
ptr[i] = i + 1;
}
// Access memory beyond the malloc'd area
printf("Accessing beyond allocated memory space...\n");
ptr[10] = 11;  // This line of code leads to heap corruption
}
return 0;
}

    Please note that the above is merely a conceptual representation of how heap corruption could occur. The actual exploitation of this vulnerability would require a much more sophisticated and malicious crafting of the file.

    Prevention and Mitigation

    The recommended mitigation for this vulnerability is to apply the vendor’s patch.
