I was looking into random driver code and found a suspicious looking memcpy() in drivers/char/ipmi/ipmi_bt_sm.c on 2.6.17-rc1: if ((size < 2) || (size > IPMI_MAX_MSG_LENGTH)) return -1; ... memcpy(bt->write_data + 3, data + 1, size - 1); where sizeof bt->write_data is IPMI_MAX_MSG_LENGTH. It looks like the memcpy would overflow by 2 bytes if size == IPMI_MAX_MSG_LENGTH. A patch attached to limit size to (IPMI_MAX_LENGTH - 2).
