Update\nsmc_ib_gid_check() to call smcr_port_err() after releasing the lock.","modified":"2026-10-19T14:16:50.487046815Z","published":"2026-10-18T16:17:08Z","upstream":["CVE-2026-98559"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98559"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-109433.json"}}],"schema_version":"1.9.0"}
