Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak exists in the flow steering list when a kernel module is removed while active entries are present. The flow steering list manages entries created and deleted as flow steering rules are added and removed. Removing the module with active entries does not properly free the associated memory, resulting in a memory leak. This is addressed by iterating through remaining entries in the list and freeing the associated memory during module removal, and by adding a spinlock (
flow steer list lock) to protect list access from multiple threads.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
