{"apiVersion":"1.0","identifier":"CVE-2026-99071","description":"In the Linux kernel, the following vulnerability has been resolved: ipv4: do not warn on route notification size race Commit 680aea08e78c (-net: ipv4: Emit notification when fib hardware flags are changed-) added asynchronous route notifications for hardware flag changes. fib_alias_hw_flags_set() sizes the skb with fib_nlmsg_size() and later fills it with fib_dump_info() while holding only RCU. With nexthop compatibility mode enabled, a concurrent replacement can grow the group between these independent snapshots. fib_dump_info() can then legitimately return -EMSGSIZE, so the warning does not prove a sizing bug. Remove the warning. The existing error path still frees the skb and reports the error to listeners.","publishedAt":"2026-10-23T13:17:31","lastModifiedAt":"2026-10-30T13:21:43","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99071","cvssScore":null,"cvssVector":null,"epssProbability":0.00206,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99071","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99071","en":"https://www.redsauce.net/en/cves/CVE-2026-99071","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99071","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99071","de":"https://www.redsauce.net/de/cves/CVE-2026-99071","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99071","el":"https://www.redsauce.net/el/cves/CVE-2026-99071"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99071"}}
