CVE-2023-54169

A flaw was found in the Linux kernel net/mlx5e Ethernet driver’s mlx5e_ptp_open function. When memory allocation via kvzalloc_node() or kvzalloc() fails, previously allocated resources (c or cparams) were not properly freed, leading to a memory leak in the error path. An unprivileged local user interacting with the networking subsystem might trigger this condition, causing gradual memory consumption.
