Title
clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe
Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe
Use devm_of_iomap() instead of of_iomap() to automatically handle
the unused ioremap region.
If any error occurs, regions allocated by kzalloc() will leak,
but using devm_kzalloc() instead will automatically free the memory
using devm_kfree().
Severity

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.
