Kernel: s390: page table upgrade in secondary address mode may lead to privilege escalation

A flaw was found in the Linux kernel on s390 architecture. The issue occurs on multiprocessing systems when one s390 CPU is in Secondary Address Mode and another CPU does a kernel page table upgrade. An inter-processor interrupt IPI is then sent to each active CPU to update the control registers...
