Ubuntu.comUB:CVE-2024-35857CVE-2024-35857
In the Linux kernel, the following vulnerability has been resolved: icmp:
prevent possible NULL dereferences from icmp_build_probe() First problem is
a double call to __in_dev_get_rcu(), because the second one could return
NULL. if (__in_dev_get_rcu(dev) && __in_dev_get_rcu(dev)->ifa_list) Second
problem is a read from dev->ip6_ptr with no NULL check: if
(!list_empty(&rcu_dereference(dev->ip6_ptr)->addr_list)) Use the correct
RCU API to fix these. v2: add missing include <net/addrconf.h>
