n 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 fib_nh_match: fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961 fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753 inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874 Separate nexthop objects are mutually exclusive with the legacy multipath spec. Fix fib_nh_match to return if the config for the to be deleted route contains a multipath spec while the fib_info is using a nexthop object.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipv4: Controlar el intento de eliminar una ruta multipath cuando fib_info contiene una referencia nh Gwangun Jung informó un acceso fuera de los límites en fib_nh_match: fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961 fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753 inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874 Los objetos de siguiente salto separados son mutuamente excluyentes con la especificación multipath heredada. Arreglar fib_nh_match para que regrese si la configuración de la ruta que se va a eliminar contiene una especificación de rutas múltiples mientras fib_info usa un objeto nexthop.
