CVE-2026-100505: Nsa Ghidra

Medium severity, CVSS 4.4. EPSS: 0.1% chance of exploitation in the next 30 days.

Ghidra versions 9.2 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 containing strings or constant byte stores that end in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output.

Affected products

• Nsa Ghidra: from 9.2, up to and including 12.1.4
