Vulnerability Title
perf/amlogic: Replace smp_processor_id() with raw_smp_processor_id() in meson_ddr_pmu_create()
来源: CVE Program / CVE List V5
Vulnerability Description
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.
Following kernel warning and stack trace:
