CVE-2026-81004: ipmi:msghandler: Cancel work cleanly on an error
In the Linux kernel, the following vulnerability has been resolved:
ipmi:msghandler: Cancel work cleanly on an error
If an error occurs during startup of an IPMI interface, it may have scheduled work to run. The work needs to be canceled before the interface can be freed.
Affected Software
Event History
Frequently Asked Questions
When can this issue be triggered?
The issue can occur when startup of an IPMI interface encounters an error after work has already been scheduled. The affected condition is tied to error handling during IPMI interface initialization.
What is the operational impact of the flaw?
Scheduled work may remain active while the IPMI interface is freed. This creates an unsafe cleanup condition involving work associated with a freed interface.
What should be done if an affected system encounters IPMI interface startup failures?
Apply a Linux kernel update that includes the referenced fix. The fix cancels scheduled work before freeing the IPMI interface when startup fails.
