I built a test kernel with commit 89a0c0ec0d2e3ce0ee9caa00f60c0c26ccf11c21. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1775390
Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

Status in Ubuntu on IBM z Systems: In Progress Status in linux package in Ubuntu: In Progress Status in linux source package in Bionic: In Progress Bug description: 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.
