CVE-2026-114044 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFX_MAP_SURFACE_TO_WINDOW_PDU with oversized dimensions, causing android_UpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
