QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
