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. (NVD)
