CVE-2026-52759Public exploit

JVM crash via unbounded Mach-O command allocation

Published Jun 10, 2026 · Updated Jun 10, 2026

Uncontrolled memory allocation in Ghidra before 12.1.1 allows attackers to crash the JVM by importing a crafted Mach-O binary. The MachHeader.parse method trusts the header's ncmds value as a loop bound and grows a command ArrayList without checking whether the file contains that many load commands. Exploitation requires an analyst or automated pipeline to import the file, causing heap exhaustion, loss of unsaved work, and interruption of the analysis session or queue.
