In commit 'c61b0743ece0' a fix was introduces to deal with varying length of the R and S integers when they are ASN1 encoded. The CAAM expect's it's input buffers to have leading zeroes. This fix however did not clear the R/S buffers which leads to uninitialized data at the start of the buffers when the ASN1 data is shorter than what the CAAM expects.
