An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-5435 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-2026-5435/ (Markdown: https://insights.sbomify.com/CVE-2026-5435/index.md)","id":"CVE-2026-5435","markdown":"https://insights.sbomify.com/CVE-2026-5435/index.md","name":"CVE-2026-5435","record":{"aliases":["AZL-84599","BELL-CVE-2026-5435","DEBIAN-CVE-2026-5435","ECHO-53d2-a97b-142d","GHSA-32rw-r8mp-pw42","MINI-2w45-2j8f-x4g4","MINI-5699-2qf6-m8cp","MINI-vq5r-m254-8qq7","ROOT-OS-DEBIAN-11-CVE-2026-5435","ROOT-OS-DEBIAN-12-CVE-2026-5435","ROOT-OS-DEBIAN-13-CVE-2026-5435","UBUNTU-CVE-2026-5435"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU C Library","requires_auth":"none","summary":"Out-of-bounds write in glibc TSIG handling allows attackers to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"glibc","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records.","ecosystems":[],"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":"Potential buffer overflow in ns_sprintrrf TSIG handling path","id":"CVE-2026-5435","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"MW WP Form \u003c= 5.1.1 - Unauthenticated Arbitrary File Move via regenerate_upload_file_keys","id":"CVE-2026-5436"},"packages":[],"prev":{"headline":"Improper storage of sensitive information","id":"CVE-2026-5434"},"products":["glibc"],"published":"2026-04-28","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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["The GNU C Library"]},"summary":"Out-of-bounds write in glibc TSIG handling allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-5435/"}
