FKIE_CVE-2024-27008
Vulnerability from fkie_nvd - Published: 2024-05-01 06:15 - Updated: 2026-06-17 07:18
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: nv04: Fix out of bounds access
When Output Resource (dcb->or) value is assigned in
fabricate_dcb_output(), there may be out of bounds access to
dac_users array in case dcb->or is zero because ffs(dcb->or) is
used as index there.
The 'or' argument of fabricate_dcb_output() must be interpreted as a
number of bit to set, not value.
Utilize macros from 'enum nouveau_or' in calls instead of hardcoding.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
