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

  - tipc: fix u16 MTU truncation in media and bearer MTU validation Both TIPC_NL_MEDIA_SET and     TIPC_NL_BEARER_SET accept user-supplied MTU values but only enforce a minimum bound, not a maximum. When a     user sets the MTU to a value exceeding U16_MAX (65535), it passes validation but is silently truncated     when assigned to u16 fields l->mtu and l->advertised_mtu in tipc_link_create(). Values like 65536     (0x10000) truncate to 0, causing a division by zero in tipc_link_set_queue_limits() which computes     TIPC_MAX_PUBL / (l->mtu / ITEM_SIZE). Other overflowing values (e.g. 65537-131071) produce small incorrect     MTU values, resulting in link malfunction behaviors. Crash stack (triggered as unprivileged user via user     namespace): tipc_link_set_queue_limits net/tipc/link.c:2531 tipc_link_create net/tipc/link.c:520     tipc_node_check_dest net/tipc/node.c:1279 tipc_disc_rcv net/tipc/discover.c:252 tipc_rcv     net/tipc/node.c:2129 tipc_udp_recv net/tipc/udp_media.c:392 Two independent paths lack the upper bound     check: 1. tipc_udp_mtu_bad() -- called from __tipc_nl_media_set() (MEDIA_SET) 2. inline check in
    __tipc_nl_bearer_set() at bearer.c:1160 (BEARER_SET) Fix both by rejecting MTU values above U16_MAX.
    (CVE-2026-68297)

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