In the Linux kernel, the following vulnerability has been resolved:
ipv4: Handle attempt to delete multipath route when fib_info contains an nh reference
Gwangun Jung reported a slab-out-of-bounds access in fibnhmatch: fibnhmatch+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fibsemantics.c:961 fibtabledelete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fibtrie.c:1753 inetrtmdelroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874
Separate nexthop objects are mutually exclusive with the legacy multipath spec. Fix fibnhmatch to return if the config for the to be deleted route contains a multipath spec while the fib_info is using a nexthop object.
