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

Description A resource leak issue has been identified in the Linux kernel, specifically in the dmaengine mv xor v2 component. The problem arises from an unbalanced clk prepare enable() call in the probe function, which lacks a corresponding clk disable unprepare() call in the remove function. This imbalance can lead to resource leaks.

Recommendations To resolve this issue, ensure that the clk disable unprepare() function is called in the remove function to balance the clk prepare enable() call made during the probe. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
