CVE-2026-16141 OpenBMC IPMI Authentication Bypass via Default userKey and Stale Challenge Value

OpenBMC's IPMI implementation, phosphor-net-ipmid, contains a logic flaw in which an unauthenticated client can force the RAKP Message 1 handler to return before it overwrites the authentication object's constructor defaults. The IPMI service then accepts a RAKP Message 3 whose HMAC is computed...

CVE-2026-81005

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. During the registration of an IPMI message handler, if the Baseboard Management Controller BMC device information cannot be fetched, a NULL pointer dereference can occur. This can allow a local attack...

Astra Linux – Vulnerability in openipmi

OpenIPMI before version 2.0.36 has a buffer overflow vulnerability related to the authentication type in the ipmisim simulator. This vulnerability can lead to denial of service, or with a very low probability authentication bypass or code execution...

Astra Linux – Vulnerability in freeipmi

In FreeIPMI, the ipmi-oem command before version 1.6.17 has exploitable buffer overflows in the response messages. The Intelligent Platform Management Interface IPMI specification defines a set of interfaces for platform management. This specification is implemented by a large number of hardware...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ipmi: ssif: Initialize ssifinfo-client early. During the probe for ssifinfo-client, it is dereferenced incorrectly. However, this initialization occurs after some error checking has already been performed. This causes a kernel...
