},
"scenarios": [
{
"lang": "en",
"value": "AV:L - The fault is reached only via the kernel system-sleep PM path (suspend/hibernate) calling dpm_suspend() -> psxpad_spi_suspend(); it is not triggered by network traffic, wireless frames, or SPI packet handling from a remote peer.\nAC:L - On embedded retro consoles/arcade cabinets with a probed psxpad-spi controller, every system suspend deterministically calls psxpad_spi_suspend() with NULL drvdata and faults in psxpad_set_motor_level(); no race, heap layout, or rare timing is required beyond CONFIG_JOYSTICK_PSXPAD_SPI hardware being present.\nPR:N - No Linux account is required on typical embedded/kiosk deployments: ACPI power-button sleep, lid-close policies, or automated idle suspend invoke the PM path without authenticated local userspace, and user namespaces cannot substitute for triggering host system sleep.\nUI:N - Exploitation requires only initiating or allowing a system suspend/hibernate cycle (power button, logind, or policy-driven sleep); no separate victim action such as opening a file, mounting a filesystem, or plugging in a controller at attack time is needed once the SPI pad is bound.\nS:U - The NULL dereference and resulting kernel oops/panic occur entirely within the same host kernel that owns the psxpad-spi driver; there is no VM escape, IOMMU/DMA boundary bypass, or cross-security-authority impact.\nC:H - psxpad_spi_suspend() passes a NULL pad into psxpad_set_motor_level(), which performs kernel stores through a NULL structure pointer; this memory-unsafe dereference class can disclose kernel memory during fault/Oops handling or on mappings where low addresses are reachable, not merely a silent crash.\nI:H - The suspend path attempts writes to pad->motor1level and pad->motor2level via a NULL base pointer, constituting attempted kernel memory corruption that can yield further write primitives or control-flow hijack on configurations without strict NULL-page protection, beyond immediate denial of service.\nA:H - The NULL pointer dereference in psxpad_set_motor_level() during psxpad_spi_suspend() causes a kernel Oops/panic that aborts or corrupts the suspend sequence, denying availability of a clean sleep/resume cycle on affected systems."
