{"id":"AZL-66890","summary":"CVE-2025-38725 affecting package kernel for versions less than 6.6.104.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: asix_devices: add phy_mask for ax88772 mdio bus\n\nWithout setting phy_mask for ax88772 mdio bus, current driver may create\nat most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.\nDLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy\ndevice will bind to net phy driver. This is creating issue during system\nsuspend/resume since phy_polling_mode() in phy_state_machine() will\ndirectly deference member of phydev-\u003edrv for non-main phy devices. Then\nNULL pointer dereference issue will occur. Due to only external phy or\ninternal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud\nthe issue.","modified":"2026-04-01T05:21:04.450653Z","published":"2025-09-04T16:15:42Z","upstream":["CVE-2025-38725"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38725"}],"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-66890.json"}}],"schema_version":"1.7.5"}
