CVE-2026-54559

A flaw was found in PocketSphinx, a small speech recognizer. Inadequate validation of boundary conditions in language model loaders and unbounded string fields in acoustic model loaders can lead to stack or heap buffer overflows and memory corruption. An attacker with write access to a directory...

CVE-2026-54559

PocketSphinx is a small speech recognizer. Prior to 5.1.1, the trie language-model loaders in src/lm/ngrammodeltrie.c do not adequately validate boundary conditions in ARPA, DMP, and binary format headers, and the acoustic-model loaders in src/mdef.c and src/util/bio.c use sscanf with unbounded...

CVE-2026-54559

PocketSphinx (a lightweight speech recognizer, including its Python bindings) versions 5prealpha through 5.1.0 are affected by buffer overflow vulnerabilities in its model-loading code. The trie language-model loaders in src/lm/ngram_model_trie.c fail to validate boundary conditions in ARPA, DMP,...

PYSEC-2026-3498 PocketSphinx: Buffer overflows in language and acoustic model loading code

Impact The trie language model code introduced in PocketSphinx 5prealpha failed to check various boundary conditions when reading the headers of ARPA, DMP, and binary format language model files. In the case of invalid, corrupted or malicious input files, this could lead to stack and heap buffer...

Heap-based Buffer Overflow

Overview pocketsphinx is an Official Python bindings for PocketSphinx Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the model loading process. An attacker can execute arbitrary code or cause a crash by supplying a crafted or malicious language or acoustic mode...
