CVE-2026-85090
FreeRDP before 3.31.0 contains a heap out-of-bounds read vulnerability in the general_ChromaV1ToYUV444 function during AVC444 chroma plane reconstruction. A malicious RDP server can craft a RFX_AVC444_BITMAP_STREAM with specific frame geometry to trigger an out-of-bounds memory read past the allocated luma plane.
