wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication
In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication The firmware-controlled rsp->count field is used as the loop bound for indexing into the flexible rsp->regs[] array without validation against the message length. A count exceeding the actual data causes out-of- bounds reads from the heap-allocated message buffer. Add a check that count fits within the received message.
