check device is present when getting link settings","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nethtool: check device is present when getting link settings\n\nA sysfs reader can race with a device reset or removal, attempting to\nread device state when the device is not actually present. eg:\n\n [exception RIP: qed_get_current_link+17]\n #8

__LINK_STATE_PRESENT (0b10).\n\nThis is the same sort of panic as observed in commit 4224cfd7fb65\n(\"net-sysfs: add check for netdevice being present to speed_show\").\n\nThere are many other callers of __ethtool_get_link_ksettings() which\ndon't have a device presence check.\n\nMove this check into ethtool to protect all callers.","state":0,"publishedAt":"2024-09-13T05:29:13.45+00:00","modifiedAt":"2026-10-15T00:50:14.512+00:00","affected":[{"ecosystem":"Vendor
