CVE-2024-58071 in Linux
الملخص
بحسب VulDB • 10/06/2026
في نواة لينكس، تم حل الثغرة التالية:
team: منع إضافة جهاز يكون بالفعل جهازًا سفليًا (lower device) لفريق (team device)
منع إضافة جهاز يكون بالفعل جهازًا سفليًا لفريق (team device lower)، على سبيل المثال، إضافة veth0 إذا كان vlan1 قد تمت إضافته مسبقًا وكان veth0 جهازًا سفليًا (lower) لـ vlan1.
هذا الإجراء غير مفيد عمليًا وقد يؤدي إلى قفل متكرر (recursive locking):
$ ip link add veth0 type veth peer name veth1 $ ip link set veth0 up $ ip link set veth1 up $ ip link add link veth0 name veth0.1 type vlan protocol 802.1Q id 1 $ ip link add team0 type team $ ip link set veth0.1 down $ ip link set veth0.1 master team0 team0: Port device veth0.1 added $ ip link set veth0 down $ ip link set veth0 master team0
