An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-0915 exists.\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-2026-0915/ (Markdown: https://insights.sbomify.com/CVE-2026-0915/index.md)","id":"CVE-2026-0915","markdown":"https://insights.sbomify.com/CVE-2026-0915/index.md","name":"CVE-2026-0915","record":{"aliases":["AZL-74633","AZL-74817","BELL-CVE-2026-0915","CLSA-2026-1772013351","CLSA-2026-1772114900","DEBIAN-CVE-2026-0915","ECHO-5e35-7adb-017f","GHSA-xp56-6525-9chf","MINI-7fpf-hm68-6c3c","MINI-px7q-p493-w5p5","MINI-rgw6-m9rq-wr8j","UBUNTU-CVE-2026-0915"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"GNU C Library","requires_auth":"none","summary":"Attackers can leak stack contents to DNS resolvers by triggering specific network queries in glibc when DNS backend is configured.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"glibc","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"Calling getnetbyaddr or getnetbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend for networks and queries for a zero-valued network in the GNU C Library version 2.0 to version 2.42 can leak stack contents to the configured DNS resolver.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-02-18","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-02-18T15:22:33Z","kind":"github_poc","ref":"https://github.com/Terra-Nova83/CVE-2026-0915-json-Patch.-V2.0","stars":0,"title":"Patch the Bug - glibc "}],"tier":"weaponised"},"has_fix":true,"headline":"getnetbyaddr and getnetbyaddr_r leak stack contents to DNS resovler","id":"CVE-2026-0915","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Related Posts by Taxonomy","id":"CVE-2026-0916"},"packages":[],"prev":{"headline":"Cross-site scripting in WP DSGVO Tools (GDPR)","id":"CVE-2026-0914"},"products":["glibc"],"published":"2026-01-15","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":"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-20","vendors":["The GNU C Library"]},"summary":"Attackers can leak stack contents to DNS resolvers by triggering specific network queries in glibc when DNS backend is configured.","url":"https://insights.sbomify.com/CVE-2026-0915/"}
