CVE-2026-49495: Loop with Unreachable Exit Condition ('Infinite Loop') in nationalsecurityagency ghidra
Ghidra 10.2 before 12.1 contains an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie() that lacks cycle detection when traversing Mach-O binary export tries. A crafted Mach-O binary with circular references in the export trie causes unbounded queue growth and exponential string concatenation, triggering OutOfMemoryError that crashes the entire JVM and loses all unsaved work.
AI Analysis
Technical Summary
CVE-2026-49495 is an uncontrolled resource consumption vulnerability in the ExportTrie.parseTrie() method of Ghidra versions 10.2 through before 12.1. The vulnerability arises because the function lacks cycle detection when traversing Mach-O binary export tries. An attacker can craft a Mach-O binary with circular references in the export trie, causing unbounded queue growth and exponential string concatenation. This triggers an OutOfMemoryError that crashes the entire Java Virtual Machine running Ghidra, resulting in loss of all unsaved work.
Potential Impact
Successful exploitation causes Ghidra's JVM to crash due to an OutOfMemoryError, leading to denial of service and loss of unsaved analysis work. There is no indication of privilege escalation or code execution. The impact is limited to resource exhaustion and application crash.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid opening untrusted or crafted Mach-O binaries that may contain circular references in export tries to prevent triggering this vulnerability.
