## Description

Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG\_ARCH\_BINFMT\_ELF\_RANDOMIZE\_PIE enabled, and a normal top-down address allocation strategy, load\_elf\_binary() will attempt to map a PIE binary into an address range immediately below mm-\>mmap\_base. Unfortunately, load\_elf\_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT\_LOAD segment is mapped below mm-\>mmap\_base, the subsequent PT\_LOAD segment(s) end up being mapped above mm-\>mmap\_base into the are that is supposed to be the "gap" between the stack and the binary.
