The Freescale EDMA driver in the Linux kernel disables its clocks twice during module removal. The first call automatically releases the clocks via devm_clk_get_enabled(), and the second call to fsl_disable_clocks() becomes redundant, triggering warning messages during driver removal. This illustrates resource mismanagement corresponding to CWE-832, though no direct security impact such as disclosure or code execution is documented.

All Linux kernel releases that include the fsl_edma driver for Freescale/NXP QorIQ platforms and are older than the commit that removes the unnecessary fsl_disable_clocks() call (commit 533d495f15e4c88ad5246c7f90ae026702e28d75) are affected. Distributions shipping such kernels should be considered vulnerable until the fix is applied.

The CVSS score is 5.5 and the EPSS score is below 1 %. The vulnerability is not in the CISA KEV catalog. Based on the description, it is inferred that unloading the fsl_edma module (the typical action that triggers the warnings) requires elevated privileges, so an attacker would need root access to trigger the issue. The overall risk is low and primarily involves benign kernel warnings, with no documented impact on confidentiality, integrity, or availability.
