      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndebugobjects: Don't call fill_pool() in early boot hardirq context\n\nWhen booting a debug PREEMPT_RT kernel on an ARM64 system, a \"inconsistent\n{HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage\" lockdep warning message was\nreported to the console.\n\nDuring early boot, interrupts are enabled before the scheduler is\nenabled. In this window (before SYSTEM_SCHEDULING is set) interrupts can\nfire and in the hard interrupt context handler attempt to fill the pool\n\nThis can lead to a deadlock when the interrupt occurred when the interrupt\nhits a region which holds a lock that is required to be taken in the\nallocation path.\n\nAdd a new can_fill_pool() helper and reorder the exception rule and forbid\nthis scenario by excluding allocations from hard interrupt context.",
