When the destination table is full and an off-link destination is reached through a default router whose neighbour cache entry is unknown, sending on an IPv6 raw socket with header inclusion dereferences a NULL pointer; a remote sender can fill the table, for example with ICMPv6 Packet Too Big messages, and crash the sending thread.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.2,"severity":"high","source":"CNA: eclipse","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"}],"modifiedAt":1793655621778,"publishedAt":1793655621778,"references":[{"source":"CNA: eclipse","tags":[],"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-9w9h-x3fh-m3fp"},{"source":"CNA: eclipse","tags":[],"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/500"}],"remediation":[],"revision":"5c2265000d248d6a22bfd3e0cb004de495637c1086d8a95e5d838ded52e550b8","sources":[{"modifiedAt":1793655621778,"name":"CNA: eclipse","retrievedAt":1793657315145,"url":"https://www.cve.org/CVERecord?id=CVE-2026-115403"}],"ssvc":null,"status":"published","title":"NULL pointer dereference in the BSD raw IPv6 send path when the destination table is full","updatedAt":1793657315145}
