Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 5.10.179/5.15.110/6.1.27/6.2.14/6.3.1. This issue affects the function of_node_put of the component ASoC. The impact remains unknown. The summary by CVE is:

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.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2023-53268 since 09/16/2025. Technical details of the vulnerability are known, but there is no available exploit.
