Subject: CVE-2026-46313: media: intel/ipu6: fix error pointer dereference
Date: Mon, 8 Jun 2026 17:49:57 +0200 [thread overview]
Message-ID: <2026060853-CVE-2026-46313-a890@gregkh> (raw)
From: Greg Kroah-Hartman <gregkh@kernel.org>
Description
===========
In the Linux kernel, the following vulnerability has been resolved:
media: intel/ipu6: fix error pointer dereference
In a error path isp->psys is confirmed to be an error pointer not NULL so
this condition is true and the error pointer is dereferenced. So isp-psys
should be set to NULL before going to out_ipu6_bus_del_devices.
Detected by Smatch:
drivers/media/pci/intel/ipu6/ipu6.c:690 ipu6_pci_probe() error:
'isp->psys' dereferencing possible ERR_PTR()
[Sakari Ailus: Fix commit message.]

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:
