CVE-2026-89822

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Guard against NULL driver_data in i915_pci_probe()
pci_match_device() can return the dummy pci_device_id_any entry when a device is force-bound via sysfs driver_override, in which case ->driver_data is unset (NULL). i915_pci_probe() casts it to struct intel_device_info * unconditionally and dereferences intel_info->require_force_probe, causing a NULL-ptr-deref.
(cherry picked from commit 2727922084672cc274ecea726ea00363c2893731)
