Action Type Old Value New Value Changed Description It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. The fork implementation in the Linux kernel before 4.5 on s390 platforms mishandles the case of four page-table levels, which allows local users to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted application, related to arch/s390/include/asm/mmu_context.h and arch/s390/include/asm/pgalloc.h.
