Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以下是该 Linux 内核漏洞描述的中文翻译： 在 Linux 内核中，以下漏洞已得到修复： crypto: keembay - 在请求 IRQ 之前初始化 completion 在初始化 之前就请求了设备的中断（IRQ）。一旦中断处理函数注册后，它可能会立即执行，而 会无条件地调用 。因此，在这个时间窗口内如果发生中断，将会使用未初始化的 completion，从而导致潜在的问题。 应在请求 IRQ 之前先初始化 completion，这与同属 OCS 的 HCU 和 ECC 驱动的做法保持一致。

Vulnerability Title
crypto: keembay - Initialize completion before requesting IRQ
Source: CVE Program / CVE List V5
Vulnerability Description
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.
