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." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/input/joystick/psxpad-spi.c" ], "versions": [ { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "e980066e434a9c74ff1665ed9140427e95b0ee7c", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "1bba6bd6861b1e0c8ecf20cd1892f0d3877c02a2", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "86531cdfb3a03213e2569deed5195412a4e3f7ee", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "da6b8b05db0cf43e0cc198431fa8ee9739b3b817", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "1edcb7ffee7ac4dc35cbe5bbd0e27bac3614ebe4", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "8d622c58205adbc8af19864e277386528b671345", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "62e25677d1440085381b047ec4984be9b6793759", "status": "affected", "versionType": "git" }, { "version": "8be193c7b1f44d3f4dcb27107df0831709c2deb1", "lessThan": "732f38c36059e68ba3b4b89c56911d777fd3185c", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/input/joystick/psxpad-spi.c" ], "versions": [ { "version": "4.12", "status": "affected" }, { "version": "0", "lessThan": "4.12", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.266", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.217", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.184", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.153", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.105", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.46", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.1.10", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "5.10.266" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "5.15.217" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.1.184" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.6.153" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.12.105" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.18.46" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "7.1.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "7.2" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/e980066e434a9c74ff1665ed9140427e95b0ee7c" }, { "url": "https://git.kernel.org/stable/c/1bba6bd6861b1e0c8ecf20cd1892f0d3877c02a2" }, { "url": "https://git.kernel.org/stable/c/86531cdfb3a03213e2569deed5195412a4e3f7ee" }, { "url": "https://git.kernel.org/stable/c/da6b8b05db0cf43e0cc198431fa8ee9739b3b817" }, { "url": "https://git.kernel.org/stable/c/1edcb7ffee7ac4dc35cbe5bbd0e27bac3614ebe4" }, { "url": "https://git.kernel.org/stable/c/8d622c58205adbc8af19864e277386528b671345" }, { "url": "https://git.kernel.org/stable/c/62e25677d1440085381b047ec4984be9b6793759" }, { "url": "https://git.kernel.org/stable/c/732f38c36059e68ba3b4b89c56911d777fd3185c" } ], "title": "Input: psxpad-spi -
