In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: handle errors in mlx5chainscreate_table()
In mlx5chainscreatetable(), the return value of mlx5getfdbsubns() and mlx5getflownamespace() must be checked to prevent NULL pointer dereferences. If either function fails, the function should log error message with mlx5corewarn() and return error pointer.
