{"id":"AZL-84225","summary":"CVE-2026-31682 affecting package kernel for versions less than 6.6.134.1-2","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbridge: br_nd_send: linearize skb before parsing ND options\n\nbr_nd_send() parses neighbour discovery options from ns-\u003eopt[] and\nassumes that these options are in the linear part of request.\n\nIts callers only guarantee that the ICMPv6 header and target address\nare available, so the option area can still be non-linear. Parsing\nns-\u003eopt[] in that case can access data past the linear buffer.\n\nLinearize request before option parsing and derive ns from the linear\nnetwork header.","modified":"2026-08-28T17:47:46.457838019Z","published":"2026-04-25T09:16:01Z","upstream":["CVE-2026-31682"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31682"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.134.1-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-84225.json"}}],"schema_version":"1.9.0"}
