Description OSIDB Bzimport 2026-01-31 12:01:32 UTC 
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.
