      "title": "drop_monitor: perform u64_stats updates under IRQ-disabled section",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrop_monitor: perform u64_stats updates under IRQ-disabled section\n\nIn net_dm_packet_trace_kfree_skb_hit() and net_dm_hw_trap_packet_probe(),\nu64_stats_update_begin() / u64_stats_inc() / u64_stats_update_end() were\ncalled after spin_unlock_irqrestore(&...drop_queue.lock, flags), when local\nIRQs had already been re-enabled.\n\nTracepoint probes can execute in IRQ or softirq context. On 32-bit\narchitectures, u64_stats_update_begin() disables preemption but not interrupts,\nrelying on seqcount writes. If a nested interrupt occurs on the same CPU during\nthe 64-bit stats update, the reentrant seqcount update can corrupt the\nseqcount state or stats value.\n\nFix this by performing the 64-bit per-CPU stats update before releasing\ndrop_queue.lock via spin_unlock_irqrestore(), ensuring local interrupts remain\ndisabled during the u64_stats update.",
