- 7.1 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Description
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.
