No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： phy: renesas: rcar-gen2：修复 PHY 创建失败时 of_node_put 被重复调用的问题 在作用域退出时会自动释放节点引用，因此 错误路径中显式调用的 会导致引用被释放两次。 请移除冗余的 ，让 scoped 清理机制自动处理引用释放。

Vulnerability Title
phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure
for_each_child_of_node_scoped() releases the node reference on scope
exit, so the explicit of_node_put(np) in the devm_phy_create() error
path drops it twice.
Drop the redundant of_node_put() and let the scoped cleanup handle it.
