When all UART_NR slots are taken, it\nreturns -EBUSY with the fifo still allocated, but the probe error\npath only kfree()s the port, leaking the transmit fifo.\n\nFree the fifo in the failure path of sdio_uart_add_port() itself so\nthe function retains nothing on error.","modified":"2026-10-07T14:17:01.989092619Z","published":"2026-10-06T09:18:07Z","upstream":["CVE-2026-98208"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98208"}],"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-106239.json"}}],"schema_version":"1.9.0"}
