Details
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: omap-dma: fix dma_pool resource leak in error paths
The dma_pool created by dma_pool_create() is not destroyed when dma_async_device_register() or of_dma_controller_register() fails, causing a resource leak in the probe error paths.
Add dma_pool_destroy() in both error paths to properly release the allocated dma_pool resource.

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.
