CVE-2026-33554:
ipmi-oem in FreeIPMI before 1.16.17 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Three subcommands were found to have exploitable buffer overflows on response messages. They are: ipmi-oem dell get-last-post- code - get the last POST code and string describing the error on some Dell servers, ipmi-oem supermicro extra-firmware-info - get extra firmware info on Supermicro servers, and ipmi-oem wistron read- proprietary-string - read a proprietary string on Wistron servers.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.
