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.] The Linux kernel CVE team has assigned CVE-2026-46313 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/media/pci/intel/ipu6/ipu6.c 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: https://git.kernel.org/stable/c/fad134c446189e9bb48cea1a5ca426d2889a9c71 https://git.kernel.org/stable/c/f43e30646fc93799f3f48530d0ccbd52902c0541 https://git.kernel.org/stable/c/c352f90e093ae49902e47f41579e1aa41899ff64 https://git.kernel.org/stable/c/8dd088b8b106f7b119664f965b691785998edcfb
