CVE-2015-4003
The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system crash) via a crafted packet.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.81%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
