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)

Improper Control of Generation of Code ('Code Injection') 🎯 Medium

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

🛡️ Empfohlene Mitigation: Refactor your program so that you do not have to dynamically generate code.
