CVE-2024-3385Network attack vector

Firewall reboot via null pointer dereference

Published Apr 10, 2024 · Updated May 13, 2026

Improper packet validation in Palo Alto Networks PAN-OS allows remote attackers to reboot PA-5400 and PA-7000 hardware firewalls. The packet-processing path dereferences a null pointer while handling untrusted network input, although the responsible protocol field and code locus are undisclosed. Only those hardware series with GTP Security disabled are exposed; repeated packets force maintenance mode and require manual recovery.
