CVE-2026-81006: Linux

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.18, before 6.18.50 (fixed in 6.18.50); from 6.19, before 7.2.4 (fixed in 7.2.4)
