Leírás forrása: CWE-119Elemzés leírás
Eredeti nyelven: 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.
