The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990768 advisory.

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

    net/x25: Fix skb leak in x25_lapb_receive_frame()

    x25_lapb_receive_frame() using skb_copy() to get a private copy of     skb, the new skb should be freed in the undersized/fragmented skb     error handling path. Otherwise there is a memory leak.
