CVE-2026-0229
A denial-of-service (DoS) vulnerability in the Advanced DNS Security (ADNS) feature of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker to initiate system reboots using a maliciously crafted packet.
Does this matter?
Lower severity and a low EPSS score (0.53%). Track it; it rarely justifies an emergency change on its own.
