This leads to a 4-byte out-of-bounds stack\nwrite in the fp[] array, which only has room for 16 elements (0–15).\n\nFix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1.","modified":"2026-04-01T05:20:59.270519Z","published":"2025-08-19T17:15:33Z","upstream":["CVE-2025-38568"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38568"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.104.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-66503.json"}}],"schema_version":"1.7.5"}
