CVE-2015-4002

25
FAUCET Score

CVE-2015-4002 is a critical vulnerability in the OZWPAN driver of the Linux kernel (versions up to 4.0.5), affecting various Linux distributions including Canonical, openSUSE, and Ubuntu. It allows remote attackers to trigger a denial of service (system crash or large loop) or potentially execute arbitrary code by sending crafted packets due to insufficient length validation in the oz_usb_rx and oz_usb_handle_ep_data functions. With a CVSS score of 9.0, this vulnerability presents a high risk due to its network-based attack vector, low attack complexity, and high impact on availability, confidentiality, and integrity. Despite its severity, there is no known active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
