  "details": "In the Linux kernel, the following vulnerability has been resolved:  firmware: qcom: scm: Fix NULL dereference in IRQ handler before __scm is published  In qcom_scm_probe(), devm_request_threaded_irq() is called before smp_store_release(\u0026__scm, scm). Two paths can dereference __scm before it is published, both causing a NULL pointer dereference.  The IRQ handler receives scm via its data argument but passes only wq_ctx to qcom_scm_waitq_wakeup() and qcom_scm_get_completion(), which then dereference __scm directly. Thread scm through both functions so the IRQ handler path never touches __scm.  Non-atomic SMC calls made during probe (e.g. from qcom_tzmem_init via qcom_scm_shm_bridge_enable) can return WAITQ_SLEEP, causing qcom_scm_wait_for_wq_completion() to run before __scm is published and dereference it. Add platform_set_drvdata(pdev, scm) early in probe and change qcom_scm_wait_for_wq_completion() to take the device pointer and use dev_get_drvdata() to reach scm, removing any dependency on __scm.",
