python
// CVE-2025-14325 PoC - JIT Miscompilation Trigger
// This PoC demonstrates a basic JIT compilation trigger pattern
// Note: Actual exploit requires specific JIT compiler error conditions
function triggerJIT() {
// Function designed to be JIT compiled
// In real exploit, specific patterns would trigger the compiler bug
let arr = [1.1, 2.2, 3.3];
let sum = 0;
for (let i = 0; i < 10000; i++) {
// Repeated operations to trigger JIT compilation
sum += arr[i % 3];
}
return sum;
}
// Force JIT compilation
for (let j = 0; j < 100; j++) {
triggerJIT();
}
// Malicious payload would be injected here
console.log('JIT compilation triggered');
