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-2026-25075 in the wild and no public exploit code.\n\nAffected product: strongSwan. 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-2026-25075/ (Markdown: https://insights.sbomify.com/CVE-2026-25075/index.md)","id":"CVE-2026-25075","markdown":"https://insights.sbomify.com/CVE-2026-25075/index.md","name":"CVE-2026-25075","record":{"aliases":["AZL-80300","DEBIAN-CVE-2026-25075","DLA-4512-1","DSA-6176-1","GHSA-frr2-5qjr-h4hw","MGASA-2026-0072","SUSE-SU-2026:0978-1","SUSE-SU-2026:0979-1","SUSE-SU-2026:0980-1","SUSE-SU-2026:0981-1","SUSE-SU-2026:1307-1","UBUNTU-CVE-2026-25075","USN-8117-1","openSUSE-SU-2026:10441-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IPsec VPN software","requires_auth":"none","summary":"Unauthenticated remote attackers can crash the strongSwan IKE daemon via crafted EAP-TTLS AVP data, causing denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication.
