Linux Kernel Flow Steering Memory Leak Vulnerability in IDPF Driver

A memory leak vulnerability has been identified in the Linux kernel's Intel IDPF Ethernet driver. This issue arises when the module is removed while flow steering entries, managed by the ethtool, are still active. The removal process fails to properly clean up the flow steering list, leading to a memory leak. The vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability causes a memory leak in the flow steering list, which can lead to increased memory usage and potential exhaustion of available memory resources.

Remediation

The vulnerability has been addressed in the Linux kernel. Users can apply the latest updates from the Linux kernel stable tree to mitigate this issue.
