CVE-2026-100505
Ghidra 11.2 through 12.1.4 Heap Out-of-Bounds Read via StringManager
Description
Ghidra versions 11.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries with constant byte stores ending in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output.
