Netatalk Heap Buffer Overflow (CVE-2026-44050) — Critical RCE Risk

title: Netatalk cnid daemon heap buffer overflow exploit attempt (CVE-2026-44050)
id: scw-2026-05-21-ai-1
status: experimental
level: critical
description: |
  Detects potential exploitation attempts against the Netatalk cnid daemon (CVE-2026-44050). This rule looks for the netatalk binary being executed with command-line arguments that might indicate a heap buffer overflow exploit targeting the comm_rcv() function. The specific exploit payload is unknown and may vary, so this rule uses a placeholder that would need to be refined with actual exploit intelligence.
