CVE-2026-81005

CVE-2026-81005 affects the Linux kernel IPMI SI driver (ipmi_si). When BMC registration fails—typically because the BMC does not return a successful response to the Get Device ID command—the shutdown_smi() callback frees the si_sm pointer and sets it to NULL , but the intf->in_shutdown flag is...

CVE-2026-81005 ipmi: si: Fix NULL pointer dereference after failed registration

In the Linux kernel, the following vulnerability has been resolved: ipmi: si: Fix NULL pointer dereference after failed registration trysmiinit allocates newsmi-sism and later calls ipmiregistersmimod, which maps to ipmiaddsmi. During ipmiaddsmi, the upper IPMI message handler obtains the initial...
