CVE-2026-118444

Out-of-bounds read vulnerabilities in the pybddisasm Python bindings may disclose adjacent process memory during instruction decoding. The nd decode function may read up to 15 bytes without checking the actual length of the supplied Python buffer. The nd decode ex, nd decode ex2, and nd decode with context functions pass the caller-supplied buffer size to the decoder without validating it against the actual length of the Python buffer. Data read beyond the buffer may be exposed through nd get instrux bytes, which returns a fixed-length list of 16 bytes. Exploitation requires an application to invoke the affected APIs with a short buffer or an oversized length and to expose the resulting bytes to an attacker. The pybddisasm package is no longer maintained.
