In the Linux kernel, the following vulnerability has been resolved: tipc: serialize udp bearer replicast list updates tipc_udp_rcast_add() and cleanup_bearer() both update ub->rcast.list with list_add_rcu() / list_del_rcu(), but nothing serializes them. The add runs from the encap receive softirq (via tipc_udp_rcast_disc()) without rtnl_lock(), so it can race the cleanup delete and corrupt the list: list_del corruption. prev->next should be ffff8880298d7ab8, but was ffff88802449ad38. (prev=ffff888027e3ec98) kernel BUG at lib/list_debug.c:62! RIP: __list_del_entry_valid_or_report+0x17a/0x200 Workqueue: events cleanup_bearer Call Trace: cleanup_bearer (net/tipc/udp_media.c:811) process_one_work (kernel/workqueue.c:3302) worker_thread (kernel/workqueue.c:3466) The bearer can be enabled from an unprivileged user namespace, as the TIPCv2 generic-netlink ops carry no GENL_ADMIN_PERM. Add a spinlock to struct udp_bearer and take it around the list_add_rcu() in tipc_udp_rcast_add() and the list_del_rcu() loop in cleanup_bearer() so the two writers can no longer corrupt the list. Reject a duplicate peer under the same lock before allocating, and remove tipc_udp_is_known_peer(). The old lockless pre-check in tipc_udp_rcast_disc() was racy: two softirqs discovering the same peer could both find it absent and add it twice. cleanup_bearer() runs from a workqueue after tipc_udp_disable() clears the bearer's up bit, so an encap softirq can still reach tipc_udp_rcast_add() and add a peer after cleanup_bearer() has already emptied the list, leaking that entry when the bearer is freed. Mark the bearer disabled under rcast_lock once the list is emptied and refuse further additions.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142724 advisory.

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

    tipc: serialize udp bearer replicast list updates

    tipc_udp_rcast_add() and cleanup_bearer() both update ub->rcast.list with     list_add_rcu() / list_del_rcu(), but nothing serializes them. The add runs     from the encap receive softirq (via tipc_udp_rcast_disc()) without     rtnl_lock(), so it can race the cleanup delete and corrupt the list:

      list_del corruption. prev->next should be ffff8880298d7ab8,         but was ffff88802449ad38. (prev=ffff888027e3ec98)       kernel BUG at lib/list_debug.c:62!       RIP: __list_del_entry_valid_or_report+0x17a/0x200       Workqueue: events cleanup_bearer       Call Trace:
       cleanup_bearer (net/tipc/udp_media.c:811)        process_one_work (kernel/workqueue.c:3302)        worker_thread (kernel/workqueue.c:3466)

    The bearer can be enabled from an unprivileged user namespace, as the     TIPCv2 generic-netlink ops carry no GENL_ADMIN_PERM.

    Add a spinlock to struct udp_bearer and take it around the list_add_rcu()     in tipc_udp_rcast_add() and the list_del_rcu() loop in cleanup_bearer() so     the two writers can no longer corrupt the list.

    Reject a duplicate peer under the same lock before allocating, and remove     tipc_udp_is_known_peer(). The old lockless pre-check in     tipc_udp_rcast_disc() was racy: two softirqs discovering the same peer     could both find it absent and add it twice.

    cleanup_bearer() runs from a workqueue after tipc_udp_disable() clears the     bearer's up bit, so an encap softirq can still reach tipc_udp_rcast_add()     and add a peer after cleanup_bearer() has already emptied the list, leaking     that entry when the bearer is freed. Mark the bearer disabled under     rcast_lock once the list is emptied and refuse further additions.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tipc: serialize udp bearer replicast list updates tipc_udp_rcast_add() and cleanup_bearer() both update     ub->rcast.list with list_add_rcu() / list_del_rcu(), but nothing serializes them. The add runs from the     encap receive softirq (via tipc_udp_rcast_disc()) without rtnl_lock(), so it can race the cleanup delete     and corrupt the list: list_del corruption. prev->next should be ffff8880298d7ab8, but was     ffff88802449ad38.

Add a spinlock to struct udp_bearer and take it around the     list_add_rcu() in tipc_udp_rcast_add() and the list_del_rcu() loop in cleanup_bearer() so the two writers     can no longer corrupt the list. Reject a duplicate peer under the same lock before allocating, and remove     tipc_udp_is_known_peer(). The old lockless pre-check in tipc_udp_rcast_disc() was racy: two softirqs     discovering the same peer could both find it absent and add it twice. cleanup_bearer() runs from a     workqueue after tipc_udp_disable() clears the bearer's up bit, so an encap softirq can still reach     tipc_udp_rcast_add() and add a peer after cleanup_bearer() has already emptied the list, leaking that     entry when the bearer is freed. Mark the bearer disabled under rcast_lock once the list is emptied and     refuse further additions. (CVE-2026-68323)

Note that Nessus relies on the presence of the package as reported by the vendor.
