CVE-2026-115394
Ghidra through 12.2 Denial of Service via BinaryField Memory Allocation
Description
Ghidra through 12.2 contains an uncontrolled memory allocation vulnerability in BinaryField.read() that allows attackers to exhaust heap memory via an unchecked 32-bit length field. Attackers can persuade users to import a crafted GZF packed database file, triggering an OutOfMemoryError in PackedDatabase.open() that aborts the import and denies service.
