{"id":"AZL-88671","summary":"CVE-2026-46037 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nipv4: icmp: validate reply type before using icmp_pointers\n\nExtended echo replies use ICMP_EXT_ECHOREPLY as the outbound reply type.\nThat value is outside the range covered by icmp_pointers[], which only\ndescribes the traditional ICMP types up to NR_ICMP_TYPES.\n\nAvoid consulting icmp_pointers[] for reply types outside that range, and\nuse array_index_nospec() for the remaining in-range lookup. Normal ICMP\nreplies keep their existing behavior unchanged.","modified":"2026-08-28T17:47:44.559687659Z","published":"2026-05-27T14:17:23Z","upstream":["CVE-2026-46037"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46037"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88671.json"}}],"schema_version":"1.9.0"}
