The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: MIPS: smp: report dying CPU to RCU in     stop_this_cpu() smp_send_stop() parks all secondary CPUs in stop_this_cpu(). The function marks the CPU     offline for the scheduler via set_cpu_online(false) but never informs RCU, so RCU keeps expecting a     quiescent state from CPUs that are now spinning forever with interrupts disabled. As long as nothing waits     for an RCU grace period after smp_send_stop() this is harmless, which is why it went unnoticed. Since     commit 91840be8f710 (irq_work: Fix use-after-free in irq_work_single() on PREEMPT_RT) however,     irq_work_sync() calls synchronize_rcu() on architectures without an irq_work self-IPI, i.e. where     arch_irq_work_has_interrupt() returns false. That is the asm-generic default used by MIPS. Any     irq_work_sync() issued in the reboot/shutdown path after smp_send_stop() then blocks on a grace period     that can never complete, hanging the reboot: WARNING: CPU: 0 PID: 15 at kernel/irq_work.c:144     irq_work_queue_on ... rcu: INFO: rcu_sched detected stalls on CPUs/tasks: rcu: Offline CPU 1 blocking     current GP. rcu: Offline CPU 2 blocking current GP. rcu: Offline CPU 3 blocking current GP. This issue was     noticed on several Realtek MIPS switch SoCs (MIPS interAptiv) and came up during kernel bump downstream in     OpenWrt from 6.18.33 to 6.18.34, after the backport of the patch to the 6.18 stable branch. The patch also     has been backported all the way back to 6.1. Call rcutree_report_cpu_dead() once interrupts are disabled,     mirroring the generic CPU-hotplug offline path, so RCU stops waiting on the parked CPUs and grace periods     can still complete. MIPS shuts down all CPUs here without going through the CPU-hotplug mechanism, so this     report is not otherwise issued. Reporting a dying CPU to RCU outside the regular hotplug offline path is     not unprecedented: arm64 does the same in cpu_die_early(). There it is an exception for a CPU that was     coming online and is aborting bringup, rather than the default shutdown action as on MIPS.
