Summary
`index()` allows out-of-bound read and `remove()` has off-by-one error
Details
Slab::index() does not perform the boundary checking, which leads to out-of-bound read access. Slab::remove() copies an element from an invalid address due to off-by-one error, resulting in memory leakage and uninitialized memory drop.

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.
