{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/77427?format=json","vulnerability_id":"VCID-5ay2-spkp-2qg1","summary":"PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc1, a heap-use-after-free is detected in the MavlinkShell::available() function. The issue is caused by a race condition between the MAVLink receiver thread (which handles shell creation/destruction) and the telemetry sender thread (which polls the shell for available output). The issue is remotely triggerable via MAVLink SERIAL_CONTROL messages (ID 126), which can be sent by an external ground station or automated script. This vulnerability is fixed in 1.17.0-rc1.","aliases":[{"alias":"CVE-2026-32724"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-32724","reference_id":"","reference_type":"","scores":[{"value":"0.00027","scoring_system":"epss","scoring_elements":"0.08118","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00027","scoring_system":"epss","scoring_elements":"0.08154","published_at":"2026-06-12T12:55:00Z"},{"value":"0.00027","scoring_system":"epss","scoring_elements":"0.0815","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00027","scoring_system":"epss","scoring_elements":"0.08149","published_at":"2026-06-14T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-32724"},{"reference_url":"https://github.com/PX4/PX4-Autopilot/security/advisories/GHSA-j5w2-w79c-mqrw","reference_id":"GHSA-j5w2-w79c-mqrw","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-16T20:08:23Z/"}],"url":"https://github.com/PX4/PX4-Autopilot/security/advisories/GHSA-j5w2-w79c-mqrw"}],"weaknesses":[{"cwe_id":416,"name":"Use After Free","description":"Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code."}],"exploits":[],"severity_range_score":"5.3 - 5.3","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-5ay2-spkp-2qg1"}
