On Broadcom BCM4355C0 Wi-Fi chips 9.44.78.27.0.1.56 and other chips, an attacker can craft a malformed RRM neighbor report frame to trigger an internal buffer overflow in the Wi-Fi firmware, aka B-V2017061204.
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.
