It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-0861 in the wild and no public exploit code.\n\nAffected product: Gnu Glibc. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-0861/ (Markdown: https://insights.sbomify.com/CVE-2026-0861/index.md)","id":"CVE-2026-0861","markdown":"https://insights.sbomify.com/CVE-2026-0861/index.md","name":"CVE-2026-0861","record":{"aliases":["AZL-74547","AZL-74636","BELL-CVE-2026-0861","CLSA-2026-1770741856","CLSA-2026-1772463357","DEBIAN-CVE-2026-0861","ECHO-9177-1522-4a81","GHSA-5pf6-63v3-88hw","MINI-3jx9-w69q-v5j9","MINI-728x-87x4-qfr5","MINI-9cxr-c34r-7965","SUSE-SU-2026:0347-1","SUSE-SU-2026:0499-1","SUSE-SU-2026:0827-1","SUSE-SU-2026:20544-1","SUSE-SU-2026:20608-1","UBUNTU-CVE-2026-0861"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU C Library","requires_auth":"none","summary":"An integer overflow in glibc's memalign functions can lead to heap corruption, potentially allowing code execution if an attacker controls both size and alignment arguments.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"glibc","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":8.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption.\n\nNote that the attacker must have control over both, the size as well as the alignment arguments of the memalign function to be able to exploit this.  The size parameter must be close enough to PTRDIFF_MAX so as to overflow size_t along with the large alignment argument.  This limits the malicious inputs for the alignment for memalign to the range [1\u003c\u003c62+ 1, 1\u003c\u003c63] and exactly 1\u003c\u003c63 for posix_memalign and aligned_alloc.\n\nTypically the alignment argument passed to such functions is a known constrained quantity (e.g. page size, block size, struct sizes) and is not attacker controlled, because of which this may not be easily exploitable in practice.  An application bug could potentially result in the input alignment being too large, e.g. due to a different buffer overflow or integer overflow in the application or its dependent libraries, but that is again an uncommon usage pattern given typical sources of alignments.","ecosystems":["SUSE:Linux Enterprise Live Patching 15 SP4","SUSE:Linux Enterprise Live Patching 15 SP5","SUSE:Linux Enterprise Live Patching 15 SP6","SUSE:Linux Enterprise Live Patching 15 SP7"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in memalign leads to heap corruption","id":"CVE-2026-0861","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"integer_overflow","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Save as PDF Plugin by PDFCrowd \u003c= 4.5.5 - Reflected Cross-Site Scripting via options","id":"CVE-2026-0862"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Live Patching 15 SP4","fixed":["0.3-150400.3.11.1"],"introduced":["0"],"last_affected":[],"package":"glibc-livepatches","purl":"pkg:rpm/suse/glibc-livepatches\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015%20SP4","source":"SUSE-SU-2026:0347-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 15 SP5","fixed":["0.3-150400.3.11.1"],"introduced":["0"],"last_affected":[],"package":"glibc-livepatches","purl":"pkg:rpm/suse/glibc-livepatches\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015%20SP5","source":"SUSE-SU-2026:0347-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 15 SP6","fixed":["0.3-150600.8.2.1"],"introduced":["0"],"last_affected":[],"package":"glibc-livepatches","purl":"pkg:rpm/suse/glibc-livepatches\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015%20SP6","source":"SUSE-SU-2026:0499-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 15 SP7","fixed":["0.3-150700.10.4.1"],"introduced":["0"],"last_affected":[],"package":"glibc-livepatches","purl":"pkg:rpm/suse/glibc-livepatches\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015%20SP7","source":"SUSE-SU-2026:0827-1"}],"prev":{"headline":"Mali GPU Kernel Driver allows access to sensitive kernel information","id":"CVE-2026-0860"},"products":["glibc"],"published":"2026-01-14","related":[{"cvss_score":9.8,"headline":"scanf %mc off-by-one heap buffer overflow","id":"CVE-2026-5450","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-25139","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-1999-0199","kev_date_added":null,"published":"2020-10-06"},{"cvss_score":9.8,"headline":"Security feature bypass in glibc","id":"CVE-2019-1010022","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2005-3590","kev_date_added":null,"published":"2019-04-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18269","kev_date_added":null,"published":"2018-05-18"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-11236","kev_date_added":null,"published":"2018-05-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-29","vendors":["The GNU C Library"]},"summary":"An integer overflow in glibc's memalign functions can lead to heap corruption, potentially allowing code execution if an attacker controls both size and alignment arguments.","url":"https://insights.sbomify.com/CVE-2026-0861/"}
