Vulnerability from fkie_nvd - Published: 2026-08-28 08:16 - Updated: 2026-08-29 07:16
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix OOB in scmi_power_name_get()
scmi_power_name_get() does not validate the domain number passed by the
external caller, which may lead to an out-of-bounds access.
Fix this by returning "unknown" for invalid domains, like
scmi_reset_name_get() does.

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.
