  affected < 2:3.10.3-5.el10_1.2fixed 2:3.10.3-5.el10_1.2

  FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, RDPEAR’s NDR array reader does not perform bounds checking on the on‑wire element count and can write past the heap buffer allocated from hints, causing a heap buffer overflow in ndr_read_uint8Array

• CVE-2026-22852CriJan 14, 2026
