Description
A flaw was found in the Linux kernel's rk3288 crypto driver. The rk_hash_run() function fails to properly handle a HASH idle timeout, ignoring the poll result. This can lead to the driver finalizing a cryptographic request with a previous success value, even if the hash engine is not idle. Consequently, incorrect cryptographic results may be returned, potentially impacting data integrity.
