ipmi: ipmb: validate write message length
In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: validate write message length ipmb_write() read message fields before validating the length byte. A zero or short write can read uninitialized stack bytes. A length smaller than the SMBus header underflows the block write length. Require a non-empty buffer and the minimum IPMB request length. Also require the length byte plus payload before parsing the message.
