Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Initialize completion before requesting IRQ kmb_ocs_aes_probe() requests the device IRQ before initializing irq_completion. Once the handler is registered it can run immediately, and ocs_aes_irq_handler() unconditionally calls complete(). An interrupt in this window would therefore use an uninitialized completion. Initialize the completion before requesting the IRQ, as the sibling OCS HCU and ECC drivers already do.
