CVE-2026-100505: Out-of-bounds Read in NationalSecurityAgency ghidra
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.
AI Analysis
Technical Summary
The vulnerability in Ghidra affects versions 11.2 through 12.1.4 and involves a heap out-of-bounds read in the StringManager::getCodepoint function. This function improperly handles decoding of multi-byte UTF-8, UTF-16, or UTF-32 characters by not validating the remaining buffer length, which allows attackers to craft binaries that cause the decompiler to read beyond allocated heap memory. This can lead to application crashes or unintended disclosure of adjacent heap memory in the decompiled output.
Potential Impact
Exploitation of this vulnerability can cause the Ghidra decompiler to crash or leak adjacent heap memory contents into the decompiled output. This may result in denial of service or unintended information disclosure. However, there are no known exploits in the wild and the CVSS score indicates a medium severity with limited attack vector (local), low complexity, and no privileges required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when analyzing untrusted binaries that may contain specially crafted multi-byte character sequences. Monitoring vendor communications for patches or updates is recommended.
