Kerentanan NULL Pointer Dereference pada qemu, redhat enterprise linux. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.
