Details

In the Linux kernel, the following vulnerability has been resolved:

spi: uniphier: Fix completion initialization order before devm_request_irq()

The driver calls devm_request_irq() before initializing the completion used by the interrupt handler. Because the interrupt may occur immediately after devm_request_irq(), the handler may execute before init_completion().

This may result in calling complete() on an uninitialized completion, causing undefined behavior. This has been observed with KASAN.

Fix this by initializing the completion before registering the IRQ.

Severity
8.4 (High)
