UBUNTU-CVE-2019-12817

arch/powerpc/mm/mmucontextbook3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected...

kernel: lack of check for mmap minimum address in expand_downwards in mm/mmap.c leads to NULL pointer dereferences exploit on non-SMAP platforms

A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits...
