{"id":"CVE-2023-46256","state":"PUBLISHED","title":"PX4-Autopilot Heap Buffer Overflow Bug","description":"PX4-Autopilot provides PX4 flight control solution for drones. 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.","publishedAt":"2023-10-31T15:29:05.943Z","updatedAt":"2024-09-05T20:15:19.837Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["PX4 PX4-Autopilot"],"affected":[{"vendor":"PX4","product":"PX4-Autopilot","versions":[{"version":"<= 1.14.0-rc1","status":"affected"}]}],"references":["https://github.com/PX4/PX4-Autopilot/security/advisories/GHSA-5hvv-q2r5-rppw","https://github.com/PX4/PX4-Autopilot/blob/main/src/drivers/distance_sensor/lightware_laser_serial/parser.cpp#L87"],"weaknesses":["CWE-122","CWE-120"],"ingestedAt":"2026-10-29T20:06:24.729Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/46xxx/CVE-2023-46256.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-46256","state":"PUBLISHED","datePublished":"2023-10-31T15:29:05.943Z","dateUpdated":"2024-09-05T20:15:19.837Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-10-19T20:34:00.949Z"},"containers":{"cna":{"title":"PX4-Autopilot Heap Buffer Overflow Bug","descriptions":[{"lang":"en","value":"PX4-Autopilot provides PX4 flight control solution for drones.
