CVE-2026-90556 is fixed in 9 products on 1 platform, first by FEDORA-2026-75BDE5D061, released September 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Freeciv versions before 3.2.6 contain a heap buffer overflow in worklist_load() when processing savegame files with declared worklist lengths exceeding the fixed array bound of 64 elements. Attackers can craft malicious savegame files that write past the entries array into adjacent heap-allocated struct fields, potentially corrupting memory when a user or server operator loads the file.
