Vulnerability from fkie_nvd - Published: 2025-07-09 11:15 - Updated: 2026-06-17 09:16

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add sanity checks for drm_edid_raw() When EDID is retrieved via drm_edid_raw(), it doesn't guarantee to return proper EDID bytes the caller wants: it may be either NULL (that leads to an Oops) or with too long bytes over the fixed size raw_edid array (that may lead to memory corruption). The latter was reported actually when connected with a bad adapter. Add sanity checks for drm_edid_raw() to address the above corner cases, and return EDID_BAD_INPUT accordingly. (cherry picked from commit 648d3f4d209725d51900d6a3ed46b7b600140cdf)

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.
