CVE-2026-52759 is a medium-severity vulnerability rated 6.7/10 on the CVSS scale. Ghidra before 12.1.1 contains an uncontrolled memory allocation vulnerability in the Mach-O binary parser that allows attackers to cause denial of service. An attacker can supply a crafted Mach-O binary with an arbitrarily large ncmds load command count value, forcing the parser to allocate excessive heap memory without validating file size, crashing the Ghidra JVM.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
