The OZWPAN driver in the Linux kernel through 4.0.5 relies on an untrusted length field during packet parsing, which allows remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read and system crash) via a crafted packet.

Security readout for executives and security teams

CVE-2015-4004 is a Linux kernel OZWPAN driver flaw. A specially crafted remote packet could make the kernel read beyond valid memory, potentially exposing sensitive kernel data or crashing the system. The provided sources do not show active exploitation or a severity score. Exposure is likely limited to systems running affected Linux kernels with the OZWPAN driver present and reachable. The source bundle does not identify specific distributions beyond Ubuntu advisories, nor confirm default enablement. Handle through normal kernel patch governance unless OZWPAN is exposed on critical systems. Escalate if affected systems are internet-adjacent, safety-critical, or difficult to reboot, because impact includes kernel data exposure and crash. Mitigation focus: Apply Linux kernel updates from Ubuntu or the relevant vendor guidance.; Prioritize systems running Linux kernel 4.0.5 or earlier with OZWPAN present.; If OZWPAN is unnecessary, review vendor-supported options to disable it..
