CVE-2026-0297: GlobalProtect App: Buffer Overflow Vulnerability during UDP Tunnel Handshake

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.59% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Palo Alto Networks GlobalProtect App 6.0.15, 6.2.8-h13, 6.3.3-h14.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Palo Alto Networks GlobalProtect App 6.0.15, 6.2.8-h13, 6.3.3-h14 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt system processes and potentially execute arbitrary code with elevated privileges (SYSTEM privileges on Windows, and root privileges on macOS and Linux).
