CVE-2026-74281NVD

Vulnerability Summary

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

tipc: reject inverted service ranges from peer bindings

tipc_update_nametbl() inserts a binding advertised by a peer node using
the lower and upper service-range bounds taken directly from the wire,
without checking that lower <= upper. The local bind path validates the
ordering (tipc_uaddr_valid()), but the name-distribution path does not.

A binding with lower > upper is inserted at the far end of the
service-range rbtree (keyed on lower) where no lookup or withdrawal can
ever match it (service_range_foreach_match() requires sr->lower <= end).
The publication, its service_range node and the augmented rbtree entry
are then leaked for the lifetime of the namespace, and there is no
per-peer cap equivalent to TIPC_MAX_PUBL on locally created bindings.

Reject inverted ranges in the network path as well. A peer node can
otherwise leak unbounded binding-table memory by sending PUBLICATION
items with lower > upper.
