It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-27803 and fix it if it is affected.\n\nWhat it is: CVE-2021-27803 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 26 Feb 2021. 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-2021-27803 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2021-27803/ (Markdown: https://insights.sbomify.com/CVE-2021-27803/index.md)","id":"CVE-2021-27803","markdown":"https://insights.sbomify.com/CVE-2021-27803/index.md","name":"CVE-2021-27803","record":{"aliases":["ALPINE-CVE-2021-27803","AZL-6973","DEBIAN-CVE-2021-27803","DLA-2581-1","GHSA-66mx-93rr-rg39","MGASA-2021-0095","OESA-2021-1133","RHSA-2021:0808","RHSA-2021:0809","RHSA-2021:0816","RHSA-2021:0818","SUSE-SU-2021:0720-1","SUSE-SU-2021:0721-1","SUSE-SU-2021:0745-1","UBUNTU-CVE-2021-27803","USN-4757-1","USN-4757-2","openSUSE-SU-2021:0404-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Wi-Fi supplicant","requires_auth":"none","summary":"An attacker within radio range can cause denial of service or execute arbitrary code via malicious P2P provision discovery requests in wpa_supplicant.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"wpa_supplicant","vendor":"w1.fi"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests.
