Description OSIDB Bzimport 2026-06-08 17:01:25 UTC

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.]
