{"id":"AZL-104835","summary":"CVE-2026-97973 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: macb: destroy the phylink instance on the probe error path\n\nmacb_mii_init() creates a phylink instance on both of its success paths,\nbut the probe unwind frees the netdev without destroying it, so a failing\nmacb_alloc_tieoff() or register_netdev() leaks the instance.\n\nDestroy it at err_out_unregister_mdio, which is only reachable once\nmacb_mii_init() has succeeded, so bp-\u003ephylink is valid there.","modified":"2026-09-27T05:34:32Z","published":"2026-09-25T11:17:25Z","upstream":["CVE-2026-97973"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97973"}],"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-104835.json"}}],"schema_version":"1.9.0"}
