ipmi:ssif: Clean up kthread on errors
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: ipmi:ssif: Clean up kthread on errors If an error occurs after the ssif kthread is created, but before the main IPMI code starts the ssif interface, the ssif kthread will not be stopped. So make sure the kthread is stopped on an error condition if it is running.

Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | MEDIUM | [email protected] |
Solution
Ensure kernel threads are stopped on error conditions to prevent resource leaks.
- Apply kernel updates to resolve the issue.
- Ensure error handling logic stops kthreads properly.
- Verify proper resource cleanup in IPMI driver.
- Test error scenarios for kthread management.
