CVE-2026-81006
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipmi: Remove all sysfs files on registration failure
ipmi_add_smi() creates the nr_users and nr_msgs files before trying to create the maintenance_mode file. If that last creation fails, the error path removes only nr_users before dropping the final reference to the interface.
Remove nr_msgs as well so no sysfs attribute embedded in the freed interface remains registered.
