^\nbond netdevsim1.100@netdevsim1 allmulticast=on (down)\nWhen we enslave the lower device (netdevsim0) which has a vlan, we\npropagate vlan's allmuti/promisc flags during ndo_open. This causes\n(re)locking on of the real_dev.\nPropagate allmulti/promisc on flags change, not on the open. There\nis a slight semantics change that vlans that are down now propagate\nthe flags, but this seems unlikely to result in the real issues.\nReproducer:\necho 0 1 > /sys/bus/netdevsim/new_device\ndev_path=$(ls -d /sys/bus/netdevsim/devices/netdevsim0/net/*)\ndev=$(echo $dev_path | rev | cut -d/ -f1 | rev)\nip link set dev $dev name netdevsim0\nip link set dev netdevsim0 up\nip link add link netdevsim0 name netdevsim0.100 type vlan id 100\nip link set dev netdevsim0.100 allm\n---truncated---", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "Oracle-Linux-7:bpftool-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-tools-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:python-perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-headers-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2025-23163" } ], "release_date": "2025-05-01T00:00:00", "scores": [ { "cvss_v3": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1" }, "products": [ "Oracle-Linux-7:bpftool-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-tools-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:python-perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-headers-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Medium" } ] } ] }
