Status in Ubuntu on IBM z Systems: Fix Committed Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Committed Bug description: == SRU Justification == Description: kernel: Fix memory leak on CCA and EP11 CPRB processing. Symptom: Kernel memory not freed when CCA or EP11 CPRB processing fails. Problem: kfree() in code error path missing. Solution: Slight rework of the malloc and free places. Reproduction: Run application which sends CCA or EP11 crypto requests to the crypto card(s). Now switch the cards offline with the help of chzcrypt. Monitor top or free output.

Limited to s390. == Test Case == Verified upfront by IBM during upstream integration.
