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-2026-75883 in the wild and no public exploit code.\n\nAffected product: ppp. 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-2026-75883/ (Markdown: https://insights.sbomify.com/CVE-2026-75883/index.md)","id":"CVE-2026-75883","markdown":"https://insights.sbomify.com/CVE-2026-75883/index.md","name":"CVE-2026-75883","record":{"aliases":["AZL-103302","BELL-CVE-2026-75883","DEBIAN-CVE-2026-75883","GHSA-rwr9-4vx8-vc35","OESA-2026-4116","OESA-2026-4117","OESA-2026-4118","UBUNTU-CVE-2026-75883"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PPP daemon","requires_auth":"none","summary":"A buffer overflow in pppd's PEAP response handling allows a malicious server to corrupt memory, likely causing a crash or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"The code in pppd that formats a response to a PEAP Request packet in peap_response() copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacket_buf\n without checking the available space and without implementing outgoing \nPEAP fragmentation.
