Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak vulnerability has been resolved in the Linux kernel. The issue occurred in the
net/mlx5e module, specifically in the mlx5 core destroy cq() function. When this function failed, it would return without completing all destroy operations, leading to a memory leak. The patch completes the destroy flow before returning an error and moves mlx5 debug cq remove() to the beginning of mlx5 core destroy cq() for symmetry with mlx5 core create cq(). The kmemleak tool complained about an unreferenced object, indicating a memory leak.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
