[REJECTED CVE] A vulnerability was identified in the Linux kernel’s Xen subsystem, where the is_xen_pmu() function failed to disable preemption while accessing a per-CPU pointer, risking undefined behavior during CPU context switches—especially during resume from suspend. Although the function takes a CPU ID parameter, it incorrectly relies on smp_processor_id(), triggering kernel warnings. An attacker could potentially exploit this through crafted suspend/resume sequences to induce instability or kernel crashes
