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

s390/zcrypt: Fix memory leak with CCA cards used as accelerator

Tests showed that there is a memory leak if CCA cards are used as accelerator for clear key RSA requests (ME and CRT). With the last rework for the memory allocation the AP messages are allocated by ap_init_apmsg() but for some reason on two places (ME and CRT) the older allocation was still in place. So the first allocation simple was never freed.
