Summary

In the Linux kernel, the following vulnerability has been resolved: powercap: intel_rapl: Fix off by one in get_rpi() The rp->priv->rpi array is either rpi_msr or rpi_tpmi which have NR_RAPL_PRIMITIVES number of elements. Thus the > needs to be >= to prevent an off by one access.

Detection rules are retrieved from Rulezet.

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.
