  "title": "usb: dwc3: gadget: fix IRQ storm on invalid event buffer count",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: dwc3: gadget: fix IRQ storm on invalid event buffer count  When dwc3_check_event_buf() reads a GEVNTCOUNT value exceeding the event buffer length, commit 63ccd26cd1f6 (\u0022usb: dwc3: gadget: check that event count does not exceed event buffer length\u0022) returns IRQ_NONE without writing back GEVNTCOUNT. Since the DWC3 interrupt is level-triggered, the uncleared IRQ source keeps the line asserted, causing a tight IRQ storm that accumulates 99,900 unhandled interrupts and triggers spurious.c:184 BUG -\u003E kernel panic.  The resulting call stack:   __report_bad_irq\u002B0xac/0xc8   note_interrupt\u002B0x340/0x468   handle_irq_event\u002B0xac/0xc0   handle_fasteoi_irq\u002B0x120/0x228   gic_handle_irq\u002B0x68/0x108   ...   kernel BUG at kernel/irq/spurious.c:184  To reproduce, write a bogus value exceeding the event buffer length directly to the GEVNTCOUNT register:    devmem \u003CDWC3_BASE \u002B 0xc40c\u003E 4 0x1004  Write the bogus count back to GEVNTCOUNT to clear the IRQ source, consistent with the stale event clearing pattern in dwc3_event_buffers_setup(), and schedule error recovery to reinitialize the controller.",
