CVE-2026-100505
Last modified
CVE-2026-100505 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. 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.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
