Subject: CVE-2026-72167: mtd: rawnand: pl353: fix probe resource allocation
Date: Sat, 15 Aug 2026 15:04:06 +0900 [thread overview]
Message-ID: <2026081537-CVE-2026-72167-d8b6@gregkh> (raw)
From: Greg Kroah-Hartman <gregkh@kernel.org>
Description
===========
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: pl353: fix probe resource allocation
During probe(), the devm_ioremap() is called with the parent device
instead of the current one. So when the module is unloaded, the register
area isn't released.
Target the pl35x device in the devm_ioremap() instead of its parent.
The Linux kernel CVE team has assigned CVE-2026-72167 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:
