来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
net: marvell: prestera: fix handling IPv4 routes with nhid
Fix handling IPv4 routes referencing a nexthop via its id by replacing
calls to fib_info_nh() with fib_info_nhc().
Trying to add an IPv4 route referencing a nextop via nhid:
$ ip link set up swp5
$ ip a a 10.0.0.1/24 dev swp5
$ ip nexthop add dev swp5 id 20 via 10.0.0.2
$ ip route add 10.0.1.0/24 nhid 20
triggers warnings when trying to handle the route:
