Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A resource leak issue has been identified in the Linux kernel, specifically in the iavf init module() function. The function fails to destroy the workqueue when pci register driver() fails, leading to a resource leak. This issue is similar to a previously fixed resource leak in the u132 hcd init function. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.
Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for the error handling in iavf init module().
As a temporary workaround, consider disabling the
iavf init module() function until a patch is available.
Restrict access to the vulnerable module to minimize the risk of exploitation.Exploit
