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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
