CVE-2024-9468Network attack vector

Service interruption via data-plane out-of-bounds write

Published Oct 9, 2024 · Updated Apr 30, 2025

An out-of-bounds write in Palo Alto Networks PAN-OS allows remote attackers to crash firewalls with a crafted data-plane packet. The data plane writes beyond a memory buffer while processing the packet; the vendor has not identified the affected routine or malformed field. Exposure requires Threat Prevention, signature 86467 on an Anti-Spyware profile, and CTD inspection of SSL handshake messages; repeated packets force maintenance mode.
