CVE-2026-49495Public exploitHinoki check available

JVM crash via cyclic Mach-O export trie

Published Jun 10, 2026 · Updated Jun 10, 2026

Uncontrolled resource consumption in Ghidra 10.2 through 12.0.4 allows context-dependent attackers to crash the JVM with a crafted Mach-O file. ExportTrie.parseTrie() repeatedly queues previously visited offsets and concatenates node names because its breadth-first traversal has no cycle detection or resource bound. Exploitation requires an analyst to import the file; the uncaught OutOfMemoryError ends GUI or headless processing and destroys unsaved work.
