RUSTSEC-2026-0029 (GHSA-J8CJ-HW74-64JV)

Vulnerability from osv_rustsec – Published: 2026-02-26 12:00 – Updated: 2026-03-01 06:01 – Source website

Summary

Double-free and use-after-free for Hive

Details

Drop implementation for Hive did perform free, but so did Hive::close, which, at the end of the scope performed Drop, therefore triggering double-free.

Additionally, function Hive::from_handle was not marked as unsafe, making it, in combination with as_handle easy to clone and trigger double-free in safe code or triggering UB when using invalid pointer.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
