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-2026-97399 in the wild and no public exploit code.\n\nAffected product: The GNU C Library 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-2026-97399/ (Markdown: https://insights.sbomify.com/CVE-2026-97399/index.md)","id":"CVE-2026-97399","markdown":"https://insights.sbomify.com/CVE-2026-97399/index.md","name":"CVE-2026-97399","record":{"aliases":["AZL-104976","DEBIAN-CVE-2026-97399","GHSA-qhjw-2xw3-v2hv","UBUNTU-CVE-2026-97399"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU C Library","requires_auth":"none","summary":"A one-byte overread in glibc's strncasecmp on Power8 can crash applications when processing attacker-controlled strings near memory boundaries.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"glibc","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"The strncasecmp function in the GNU C Library 2.24 and later optimized for the Power8 architecture may read one byte beyond the input size limit, which may crash a program when that byte is not readable.\n\nThis condition may happen when the input strings to the strncasecmp function are attacker controlled in an application and they match all the way up to the edge of their page and the neighbouring page is either not mapped or is not readable.","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":"One-byte overread in strncasecmp on Power8","id":"CVE-2026-97399","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"In Eclipse OpenJ9 versions up to 0.63, opening a supplied diagnostic dump bundle with the jdmpview tool, or equivalent DTFJ code, may cause","id":"CVE-2026-97400"},"packages":[],"prev":{"headline":"Cross-site scripting in FV Flowplayer Video Player","id":"CVE-2026-97398"},"products":["glibc"],"published":"2026-09-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-28","vendors":["The GNU C Library"]},"summary":"A one-byte overread in glibc's strncasecmp on Power8 can crash applications when processing attacker-controlled strings near memory boundaries.","url":"https://insights.sbomify.com/CVE-2026-97399/"}
