Description
In the Linux kernel, the following vulnerability has been resolved: idpf: fix memory leak of flow steer list on rmmod The flow steering list maintains entries that are added and removed as ethtool creates and deletes flow steering rules. Module removal with active entries causes memory leak as the list is not properly cleaned up. Prevent this by iterating through the remaining entries in the list and freeing the associated memory during module removal. Add a spinlock (flow_steer_list_lock) to protect the list access from multiple threads.

Executive Summary

This vulnerability is a memory leak in the Linux kernel related to the idpf module's flow steering list. When the module is removed (rmmod) while there are still active entries in the flow steering list, the memory allocated for these entries is not properly freed, causing a memory leak. The fix involves iterating through the list during module removal to free the associated memory and adding a spinlock to protect the list from concurrent access.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion if the module is frequently removed without proper cleanup. This could affect system stability and reliability.

Mitigation Strategies

To mitigate this vulnerability, update the Linux kernel to a version where the idpf module properly frees the flow steer list memory during module removal. Avoid removing the idpf module while flow steering rules are active to prevent memory leaks.
