Summary

ipmi: ipmb: validate write message length

Details

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 length smaller than the SMBus header underflows the block write length.
