Subject: CVE-2022-49457: ARM: versatile: Add missing of_node_put in dcscb_init
Date: Wed, 26 Feb 2025 03:12:11 +0100 [thread overview]
Message-ID: <2025022600-CVE-2022-49457-0a07@gregkh> (raw)
Description
===========
In the Linux kernel, the following vulnerability has been resolved:
ARM: versatile: Add missing of_node_put in dcscb_init
The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak.
The Linux kernel CVE team has assigned CVE-2022-49457 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
