CVE-2026-50538: CWE-122: Heap-based Buffer Overflow in LibVNC libvncserverCVE-2026-50538 0 CVE-2026-50538 is a heap-based buffer overflow vulnerability in LibVNCClient versions 0.9.12 through 0.9.15. A malicious or man-in-the-middle VNC server can exploit this flaw by sending a crafted FramebufferUpdate message that causes libvncclient to write attacker-controlled data beyond the framebuffer boundary. This vulnerability requires no authentication and triggers immediately upon connection, causing a crash (denial of service) or potentially allowing remote code execution by overwriting application callback pointers.
