Description OSIDB Bzimport 2025-09-16 09:03:22 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: fsl_mqs: move of_node_put() to the correct location

of_node_put() should have been done directly after
mqs_priv->regmap = syscon_node_to_regmap(gpr_np);
otherwise it creates a reference leak on the success path.

To fix this, of_node_put() is moved to the correct location, and change
all the gotos to direct returns.
