{"id":"CVE-2026-86714","summary":"PX4 Autopilot through 1.17.0 Stack Buffer Over-read via netman","details":"PX4 Autopilot through 1.17.0 contains a stack buffer over-read vulnerability in the netman system command that fails to validate interface name length. Attackers can supply interface names of 74 bytes or more via the -i option to read beyond buffer boundaries, leaking stack memory to console output or writing it into persistent network configuration files.","modified":"2026-09-10T08:14:34.923285Z","published":"2026-09-08T11:23:06.416Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86714.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86714.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86714"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/px4-autopilot-through-1.17.0-stack-buffer-over-read-via-netman"},{"type":"FIX","url":"https://github.com/PX4/PX4-Autopilot/commit/fec216e9d716d96d93b9d882b0c9cf00db3c6810"},{"type":"FIX","url":"https://github.com/PX4/PX4-Autopilot/pull/28483"},{"type":"PACKAGE","url":"https://github.com/PX4/PX4-Autopilot"},{"type":"ARTICLE","url":"https://github.com/PX4/PX4-Autopilot/blob/v1.17.0/src/systemcmds/netman/netman.cpp"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/px4/px4-autopilot","events":[{"introduced":"0"},{"fixed":"d6f12ad1c4f70ad3230afd7d86e971421e02fef4"},{"fixed":"fec216e9d716d96d93b9d882b0c9cf00db3c6810"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.17.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v1.18.0-beta1","v1.18-beta1","v1.18.0-alpha1","v1.17.0-rc2","v1.17.0-rc1","v1.17.0-beta1","v1.17.0-alpha1","v1.16.0-rc1","v1.16.0-beta1","v1.16.0-alpha2","v1.16.0-alpha1","v1.15.0-beta1","v1.15.0-alpha1","v1.14.0-beta2","v1.14.0-beta1","v1.13.0-beta1","v1.12.0-rc1","v1.12.0","v1.13.0-alpha1","v1.12.0-beta6","v1.12.0-beta5","v1.12.0-beta4","v1.12.0-beta3","v1.12.0-beta2","v1.11.0-rc3","v1.11.0-rc2","v1.11.0-rc1","v1.11.0-beta2","v1.11.0-beta1","v1.10.0-beta4","v1.10.0-beta3","v1.10.0-beta2","v1.10.0-beta1","v1.9.0-rc2","v1.9.0","v1.9.0-rc1","v1.9.0-rc0","v1.9.0-beta3","v1.9.0-beta2","v1.9.0-beta1","v1.9.0-alpha","v1.8.0","v1.8.0-rc0","v1.8.0-beta2","v1.8.0-beta1","v1.7.4beta","v1.7.3","v1.7.3beta","v1.7.2","v1.7.1","v1.7.0","v1.7.0-rc4","v1.7.0-rc3","v1.7.0-rc2","v1.7.0-rc1","v1.7.0-rc0","v1.6.5","v1.6.4","v1.6.2","v1.6.0-rc4","v1.6.0-rc3","v1.6.0-rc2","v1.6.0rc1","v1.5.2","v1.5.1","v1.5.1rc4","v1.5.1rc3","v1.5.1rc2","v1.5.0","v1.4.4rc1","v1.4.3","v1.4.2","v1.4.1","v1.4.1rc4","v1.4.1rc3","v1.4.1rc2","v1.4.1rc1","v1.4.0rc4","v1.4.0rc3","v1.4.0rc2","v1.4.0rc1","v1.3.2","v1.3.0rc3","v1.3.0rc2","v1.3.0rc1","v1.1.3","v1.1.2","v1.1.1","v1.1.0beta3","v1.1.0beta1","v1.0.0beta2","v1.0.0rc12","v1.0.0rc9","v1.0.0rc10","v1.0.0rc8","v1.0.0rc7","v1.0.0-rc3","v1.0.0-rc2","v1.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86714.json","vanir_signatures_modified":"2026-09-10T08:14:34Z","vanir_signatures":[{"target":{"file":"src/systemcmds/netman/netman.cpp"},"deprecated":false,"digest":{"line_hashes":["192525564398829838223569083702630084299","272380454600619172136188934227804417625","43559798722479495689292405321570281256","280948252679040416074309252621556435747","230726104032542036209914144505729144726","275055182552866223856459987630725594134","300860300972712222567949263737001222255","58776563248557625159905291433709364868"],"threshold":0.9},"id":"CVE-2026-86714-223b9ab8","signature_type":"Line","signature_version":"v1","source":"https://github.com/px4/px4-autopilot/commit/fec216e9d716d96d93b9d882b0c9cf00db3c6810"},{"id":"CVE-2026-86714-b2699b2b","signature_type":"Function","signature_version":"v1","source":"https://github.com/px4/px4-autopilot/commit/fec216e9d716d96d93b9d882b0c9cf00db3c6810","target":{"file":"src/systemcmds/netman/netman.cpp","function":"netman_main"},"deprecated":false,"digest":{"function_hash":"29987183945868084463430304557510719868","length":771}}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
