An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-0934 and fix it if it is affected.\n\nWhat it is: CVE-2022-0934 is a high-severity use after free vulnerability in Redhat Enterprise Linux, published on 29 Aug 2022. 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-2022-0934 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise Linux. 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-2022-0934/ (Markdown: https://insights.sbomify.com/CVE-2022-0934/index.md)","id":"CVE-2022-0934","markdown":"https://insights.sbomify.com/CVE-2022-0934/index.md","name":"CVE-2022-0934","record":{"aliases":["ALPINE-CVE-2022-0934","ALSA-2022:7633","ALSA-2022:8070","AZL-25317","CLEANSTART-2026-LH68437","CLSA-2026-1778157268","DEBIAN-CVE-2022-0934","GHSA-wpmh-x6rm-9p34","MGASA-2022-0233","OESA-2022-1761","RHSA-2022:7633","RHSA-2022:8070","RLSA-2022:7633","RLSA-2022:8070","SUSE-SU-2022:1307-1","UBUNTU-CVE-2022-0934","USN-5408-1","openSUSE-SU-2024:11998-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS and DHCP server","requires_auth":"none","summary":"An attacker can cause a denial of service in dnsmasq by sending a crafted packet that triggers a use-after-free flaw.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"enterprise_linux","vendor":"redhat"},{"product":"dnsmasq","vendor":"thekelleys"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-416","name":"Use After Free"}],"description":"A single-byte, non-arbitrary write/use-after-free flaw was found in dnsmasq.
