AI Analysis
Technical Summary
CVE-2026-0297 is a CWE-787 out-of-bounds write vulnerability in Palo Alto Networks GlobalProtect app versions 6.0.0, 6.2.0, and 6.3.0. It enables a man-in-the-middle attacker or rogue gateway to cause a buffer overflow, disrupting system processes and potentially executing arbitrary code with elevated privileges (SYSTEM on Windows, root on macOS and Linux). The vulnerability has a CVSS 4.0 base score of 5.2 (medium severity). No vendor advisory or patch information is available, and no known exploits have been reported.
Potential Impact
Successful exploitation could allow an attacker positioned as a man-in-the-middle or operating a rogue gateway to disrupt system processes and execute arbitrary code with elevated privileges on affected systems. This could lead to full system compromise on Windows, macOS, and Linux devices running the vulnerable GlobalProtect app versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should be cautious of connecting to untrusted networks or gateways and monitor for vendor updates.
