    "summary": "In the Linux kernel, the following vulnerability has been resolved: ipc: fix memleak if msg_init_ns failed in create_ipc_ns Percpu memory allocation may failed during create_ipc_ns however this fail is not handled properly since ipc sysctls and mq sysctls is not released properly. Fix this by release these two resource when failure.
