Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak issue has been identified in the Linux kernel, specifically in the imx-sdma component of the dmaengine.

The issue has been observed in cases where a timeout waiting for CH0 ready occurs, as indicated by a log message.
