The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - net: ipv4: fix one memleak in __inet_del_ifa() I got the below warning when do fuzzing test:
    unregister_netdevice: waiting for bond0 to become free. Usage count = 2 It can be repoduced via: ip link     add bond0 type bond sysctl -w net.ipv4.conf.bond0.promote_secondaries=1 ip addr add 4.117.174.103/0 scope     0x40 dev bond0 ip addr add 192.168.100.111/255.255.255.254 scope 0 dev bond0 ip addr add 0.0.0.4/0 scope     0x40 secondary dev bond0 ip addr del 4.117.174.103/0 scope 0x40 dev bond0 ip link delete bond0 type bond     In this reproduction test case, an incorrect 'last_prim' is found in __inet_del_ifa(), as a result, the     secondary address(0.0.0.4/0 scope 0x40) is lost. The memory of the secondary address is leaked and the     reference of in_device and net_device is leaked. Fix this problem: Look for 'last_prim' starting at     location of the deleted IP and inserting the promoted IP into the location of 'last_prim'.
