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-2026-1757 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-1757/ (Markdown: https://insights.sbomify.com/CVE-2026-1757/index.md)","id":"CVE-2026-1757","markdown":"https://insights.sbomify.com/CVE-2026-1757/index.md","name":"CVE-2026-1757","record":{"aliases":["BELL-CVE-2026-1757","DEBIAN-CVE-2026-1757","ECHO-c488-0c15-5961","GHSA-7qq5-wfv8-hvvh","OESA-2026-1774","UBUNTU-CVE-2026-1757"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"A memory leak in the xmllint interactive shell allows local attackers to exhaust system memory and cause a denial of service by repeatedly submitting whitespace input.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to free the allocated buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system memory and terminate the xmllint process, creating a denial-of-service condition on the local system.","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":"Libxml2: memory leak leading to local denial of service in xmllint interactive shell","id":"CVE-2026-1757","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Session Fixation","id":"CVE-2026-1758"},"packages":[],"prev":{"headline":"WP FOFT Loader \u003c= 2.1.39 - Authenticated (Author+) Arbitrary File Upload","id":"CVE-2026-1756"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Hardened Images","Red Hat JBoss Core Services","Red Hat OpenShift Container Platform 4"],"published":"2026-02-02","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":"2026-09-01","vendors":["Red Hat"]},"summary":"A memory leak in the xmllint interactive shell allows local attackers to exhaust system memory and cause a denial of service by repeatedly submitting whitespace input.","url":"https://insights.sbomify.com/CVE-2026-1757/"}
