CVE-2025-38536 – “Airoha Linux Kernel Use-After-Free Vulnerability”

In the Linux kernel, the following vulnerability has been resolved:

net: airoha: fix potential use-after-free in airoha_npu_get()

np->name was being used after calling of_node_put(np), which
releases the node and can lead to a use-after-free bug.
Previously, of_node_put(np) was called unconditionally after
of_find_device_by_node(np), which could result in a use-after-free if
pdev is NULL.

This patch moves of_node_put(np) after the error check to ensure
the node is only released after both the error and success cases
are handled appropriately, preventing potential resource issues.
