An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011148 advisory.

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

    net: hsr: avoid possible NULL deref in skb_clone()

    syzbot got a crash [1] in skb_clone(), caused by a bug     in hsr_get_untagged_frame().

    When/if create_stripped_skb_hsr() returns NULL, we must     not attempt to call skb_clone().

    While we are at it, replace a WARN_ONCE() by netdev_warn_once().
