{"id":"CVE-2017-1000253","aliases":[],"url":"https://o3.security/vulnerability/CVE-2017-1000253","summary":null,"details":"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.","published":"2017-10-05T01:29:04.790Z","modified":"2026-03-15T22:13:28.547840Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.10695,"percentile":0.95587,"asOf":"2026-09-17"},"cisaKev":{"dateAdded":"2024-09-09","dueDate":"2024-09-30","knownRansomwareCampaignUse":true},"exploitsKnown":5,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2017-1000253"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2798"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2799"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1039434"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2793"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2794"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2796"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2797"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2800"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2801"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2802"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/101010"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2795"},{"type":"FIX","url":"https://www.qualys.com/2017/09/26/cve-2017-1000253/cve-2017-1000253.txt"}],"provenance":{"sources":["OSV.dev","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-03-15T22:13:28.547840Z"}}
