What is CVE-2026-89822?
CVE-2026-89822 is a vulnerability in Linux, published on 16 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
