CVE-2026-39929

Lakeside SysTrack Agent versions prior to 11.2.1.28, 11.3.0.38, 11.4.0.24, 11.5.0.15 contain an out-of-bounds read vulnerability in the Command ID 30 UDP packet handler that allows remote attackers to crash the application by sending a specially crafted UDP packet. Attackers can send a malformed packet with an invalid memory address at offset 0x4 in the payload to trigger an access violation and cause a denial of service.
