In versions 1.14.0-rc1 and prior, PX4-Autopilot has a heap buffer overflow vulnerability in the parser function due to the absence of `parserbuf_index` value checking. A malfunction of the sensor device can cause a heap buffer overflow with leading unexpected drone behavior. Malicious applications can exploit the vulnerability even if device sensor malfunction does not occur. Up to the maximum value of an `unsigned int`, bytes sized data can be written to the heap memory area. As of time of publication, no fixed version is available."}],"source":{"advisory":"GHSA-5hvv-q2r5-rppw","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T20:37:40.220Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/PX4/PX4-Autopilot/security/advisories/GHSA-5hvv-q2r5-rppw","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/PX4/PX4-Autopilot/security/advisories/GHSA-5hvv-q2r5-rppw"},{"name":"https://github.com/PX4/PX4-Autopilot/blob/main/src/drivers/distance_sensor/lightware_laser_serial/parser.cpp#L87","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/PX4/PX4-Autopilot/blob/main/src/drivers/distance_sensor/lightware_laser_serial/parser.cpp#L87"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-05T20:15:11.311094Z","id":"CVE-2023-46256","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-05T20:15:19.837Z"}}]}}
