KB5041054: This update fixes a known issue that affects the BCryptSignHash API.

Improvements

• This update fixes a known issue affecting the BCryptSignHash API. Due to this issue, the API returns "STATUS_INVALID_PARAMETER". This occurs when callers use NULL padding input parameters for RSA signatures. This issue is more likely to occur if customer managed keys (CMK) are used, e.g. in a dedicated SQL pool of Azure Synapse.
