FAUCET Score

CVE-2017-4925 is a NULL pointer dereference vulnerability affecting VMware ESXi (versions 5.5, 6.0, 6.5), Workstation (12.x), and Fusion (8.x). This medium-severity flaw (CVSS 5.5) allows attackers with normal user privileges to crash their virtual machines by sending specially crafted guest RPC requests. While the vulnerability has a low attack complexity and no confidentiality or integrity impact, it can lead to a denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV catalog listing, and it has received minimal community discussion and media coverage.
