Description OSIDB Bzimport 2025-12-30 13:17:51 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: fix memory leak in mlx5e_ptp_open

When kvzalloc_node or kvzalloc failed in mlx5e_ptp_open, the memory
pointed by "c" or "cparams" is not freed, which can lead to a memory
leak. Fix by freeing the array in the error path.
