CVE-2026-115397: Ghidra resource allocation without limits in extension extraction

CVE-2026-115397 · Severity: medium · CVSS 5.5 · Published 2026-10-22

Ghidra is a reverse-engineering framework used by security researchers and analysts. The vulnerability allows attackers to craft a malicious extension archive that, when installed by a user, extracts an excessive number of files and exhausts the system's available filesystem inodes, causing the application and other processes to fail to write files or function properly.

Technologies: National Security Agency Ghidra. Vendors: National Security Agency.

Technical details

The ExtensionUtils.unzipToInstallationFolder() method fails to limit the number of files extracted from a ZIP archive, allowing a crafted extension to exhaust filesystem inodes. The attack requires user interaction (installing an extension) and is preceded by a network delivery of the malicious archive. A successful exploit denies service to Ghidra project writes and other filesystem-dependent operations.
