Vulnerability from github – Published: 2026-07-24 18:31 – Updated: 2026-08-12 00:31

Details

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

phy: qcom: qmp-usbc: Fix out-of-bounds array access in dp swing config

swing_tbl and pre_emphasis_tbl are 4x4 arrays (valid indices 0-3), but the boundary check uses "> 4" instead of ">= 4", allowing index 4 to cause an out-of-bounds access.

Severity

7.1 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

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.
