{"apiVersion":"1.0","identifier":"CVE-2026-74281","description":"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.","publishedAt":"2026-08-15T06:22:27","lastModifiedAt":"2026-08-17T06:19:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74281","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00662,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74281","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74281","en":"https://www.redsauce.net/en/cves/CVE-2026-74281","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74281","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74281","de":"https://www.redsauce.net/de/cves/CVE-2026-74281","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74281","el":"https://www.redsauce.net/el/cves/CVE-2026-74281"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74281"}}
