## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
