Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: sun8i-ss - Fix memory leak of object d when dma_iv fails to map

In the case where the dma_iv mapping fails, the return error path leaks the memory allocated to object d. Fix this by adding a new error return label and jumping to this to ensure d is free'd before the return.

Addresses-Coverity: ("Resource leak")
