CVE-2025-38295

High

In the Linux kernel, the following vulnerability has been resolved: perf/amlogic: Replace smp_processor_id() with raw_smp_processor_id() in meson_ddr_pmu_create() The Amlogic DDR PMU driver meson_ddr_pmu_create() function incorrectly uses smp_processor_id(), which assumes disabled preemption. This leads to kernel warnings during module loading because meson_ddr_pmu_create() can be called in a preemptible context.
