Описание
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.
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.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
