On the Broadcom Wi-Fi HardMAC SoC with fbt firmware, a stack buffer overflow occurs when handling an 802.11r (FT) authentication response, leading to remote code execution via a crafted access point that sends a long R0KH-ID field in a Fast BSS Transition Information Element (FT-IE).
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.
