**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A bug in the Linux kernel has been resolved, specifically in the tegra20-emc module. The issue arises from the `tegra emc find node by ram code()` function releasing device nodes while they are still in use, potentially leading to use-after-free (UAF) errors. This occurs because `of find node by name()` releases the reference of the argument device node. To fix this, the code has been simplified using the `for each child of node()` macro and `of get child by name()` instead of `of find node by name()`. The bug was discovered using an experimental verification tool. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
