Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted packet.

Security readout for executives and security teams

CVE-2015-4001 is a Linux kernel flaw in the OZWPAN driver. A crafted packet could crash an affected system and may allow arbitrary code execution. Business risk depends heavily on whether the OZWPAN driver exists and is reachable on deployed Linux systems. Exposure is most likely on older Linux systems running kernels through 4.0.5 with the OZWPAN driver present, enabled, and reachable by crafted packets. The source bundle does not provide a complete product matrix or distribution version list. Treat this as a legacy Linux kernel remediation issue with potentially severe impact on exposed systems. Prioritize confirmation and patching where the OZWPAN driver is enabled; broad emergency action is not supported without exposure evidence. Mitigation focus: Apply kernel updates from the relevant Linux distribution advisory.; Confirm the deployed kernel contains upstream commit b1bb5b49373b61bf9d2c73a4d30058ba6f069e4c.; Prioritize systems where the OZWPAN driver is installed, enabled, or exposed..
