CVE-2026-46108

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI System Interface SI driver. This vulnerability occurs when the driver fails to return to a normal operational state after a message allocation failure. This improper state handling can lead to the driver not...

CVE-2026-46128

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. This vulnerability occurs when the kernel processes event message buffer responses from Baseboard Management Controllers BMCs. Some BMCs may return an empty message instead of an expected error, which...

CVE-2026-46177

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI driver. This vulnerability allows a malfunctioning Baseboard Management Controller BMC to cause the IPMI driver to continuously fetch events and messages, or become stuck if the attention bit remains active. Thi...

CVE-2026-46128

The CVE-2026-46128 issue concerns the Linux kernel IPMI event message handling. The root cause is an insufficiently validated event message buffer/data size occurring when fetching events, with some BMCs returning an empty message instead of an error. This leads to a potential failure in processi...
