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

在 Linux 内核中，已修复以下漏洞： crypto: rk3288 - 在 HASH 空闲超时失败处理 ahash 请求 在最终 DMA 传输后等待 变为空闲状态，但忽略了轮询结果。如果哈希引擎始终未变为空闲，驱动程序仍会读取摘要（digest）寄存器，并使用之前的成功值来结束请求。 修复方式：保存轮询结果，并在读取摘要寄存器之前，根据超时错误结束请求。

Vulnerability Title
crypto: rk3288 - fail ahash requests on HASH idle timeout
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: crypto: rk3288 - fail ahash requests on HASH idle timeout rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the final DMA transfer, but ignores the poll result. If the hash engine never becomes idle, the driver still reads the digest registers and finalizes the request with the previous success value. Store the poll result and finalize the request with the timeout error before reading the digest registers.
