EricLBuehler Mistral.rs up to 0.8.22. Affected by this issue is the function convert_gguf_to_hf_tokenizer of the file mistralrs-core/src/gguf/gguf_tokenizer.rs of the component GGUF Tokenizer. The manipulation of the argument eos_token_id/bos_token_id/unknown_token_id results in out-of-bounds read. The attack can be executed remotely. The exploit is now public and may be used. Upgrading to version 0.8.23 can resolve this issue. The patch is identified as cd5297e2ea5cb27c790bdcf2f3c2f1064a81d55e. Upgrading the affected component is recommended."}], "lastModified": "2026-08-20T12:48:10.287", "sourceIdentifier": "cna@vuldb.com"}
