CVE-2024-57801

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Skip restore TC rules for vport rep without loaded flag

During driver unload, unregister_netdev is called after unloading
vport rep. So, the mlx5e_rep_priv is already freed while trying to get
rpriv->netdev, or walk rpriv->tc_ht, which results in use-after-free.
So add the checking to make sure access the data of vport rep which is
still loaded.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
