CVE-2023-53268

Medium

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.
