Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a memory leak in the
net/mlx5e module related to Traffic Control (TC). Specifically, when flow rules are split and extra post act rules are added to the post act table, a memory leak can occur when forwarding packets from an internal port over a tunnel, particularly when CT 'new' state offload is enabled. This happens because the reference count of the internal port object is incremented but not decremented, preventing the object from being freed. The issue is triggered during the addition of flow rules and involves functions like mlx5e tc int port get() and mlx5e tc int port put(). The kernel memory leak reports an unreferenced object of size 64 bytes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
