CVE-2017-16911

16
FAUCET Score

CVE-2017-16911 describes a kernel memory address disclosure vulnerability in the vhci_hcd driver of the Linux Kernel, affecting versions prior to 4.14.8 and 4.4.114. This medium-severity vulnerability (CVSS 4.7) requires a local attacker and the attachment of a USB device over IP, making exploitation moderately complex. While it allows for high confidentiality impact by revealing kernel memory addresses, it does not impact integrity or availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
