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-2026-6554 in the wild and no public exploit code.\n\nAffected product: The Tcpdump Group libpcap. 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-2026-6554/ (Markdown: https://insights.sbomify.com/CVE-2026-6554/index.md)","id":"CVE-2026-6554","markdown":"https://insights.sbomify.com/CVE-2026-6554/index.md","name":"CVE-2026-6554","record":{"aliases":["ALPINE-CVE-2026-6554","AZL-99747","AZL-99924","BELL-CVE-2026-6554","DEBIAN-CVE-2026-6554","ECHO-7550-c016-c10c","GHSA-2c9f-8whq-v3fc","UBUNTU-CVE-2026-6554"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Packet capture library","requires_auth":"low_privilege","summary":"A crafted BPF filter program can cause an infinite loop in the libpcap interpreter, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Tcpdump","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations.
