      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: dwc3: gadget: fix IRQ storm on invalid event buffer count\n\nWhen dwc3_check_event_buf() reads a GEVNTCOUNT value exceeding the\nevent buffer length, commit 63ccd26cd1f6 (\"usb: dwc3: gadget: check\nthat event count does not exceed event buffer length\") returns IRQ_NONE\nwithout writing back GEVNTCOUNT. Since the DWC3 interrupt is\nlevel-triggered, the uncleared IRQ source keeps the line asserted,\ncausing a tight IRQ storm that accumulates 99,900 unhandled interrupts\nand triggers spurious.c:184 BUG -> kernel panic.\n\nThe resulting call stack:\n  __report_bad_irq+0xac/0xc8\n  note_interrupt+0x340/0x468\n  handle_irq_event+0xac/0xc0\n  handle_fasteoi_irq+0x120/0x228\n  gic_handle_irq+0x68/0x108\n  ...\n  kernel BUG at kernel/irq/spurious.c:184\n\nTo reproduce, write a bogus value exceeding the event buffer length\ndirectly to the GEVNTCOUNT register:\n\n  devmem <DWC3_BASE + 0xc40c> 4 0x1004\n\nWrite the bogus count back to GEVNTCOUNT to clear the IRQ source,\nconsistent with the stale event clearing pattern in\ndwc3_event_buffers_setup(), and schedule error recovery to\nreinitialize the controller.",
