Vulnerability from github – Published: 2024-08-17 12:30 – Updated: 2025-02-03 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: mxs-dcp - Ensure payload is zero when using key slot

We could leak stack memory through the payload field when running AES with a key from one of the hardware's key slots. Fix this by ensuring the payload field is set to 0 in such cases.

This does not affect the common use case when the key is supplied from main memory via the descriptor payload.

Severity

7.1 (High)

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.
