  "summary": "spi: uniphier: Fix completion initialization order before devm_request_irq()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: uniphier: Fix completion initialization order before devm_request_irq()\n\nThe driver calls devm_request_irq() before initializing the completion\nused by the interrupt handler. Because the interrupt may occur immediately\nafter devm_request_irq(), the handler may execute before init_completion().\n\nThis may result in calling complete() on an uninitialized completion,\ncausing undefined behavior. This has been observed with KASAN.\n\nFix this by initializing the completion before registering the IRQ.",
