Title
dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get()
Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get()
We should call of_node_put() for the reference returned by
of_parse_phandle() in fail path or when it is not used anymore.
Here we only need to move the of_node_put() before the check.
Severity
No CVSS data available.

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.
