VUL-0: CVE-2024-40993: kernel: netfilter: ipset: Fix suspicious rcu_dereference_protected()
Last modified: 2024-07-15 12:41:48 UTC
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix suspicious rcu_dereference_protected() When destroying all sets, we are either in pernet exit phase or are executing a "destroy all sets command" from userspace. The latter was taken into account in ip_set_dereference() (nfnetlink mutex is held), but the former was not. The patch adds the required check to rcu_dereference_protected() in ip_set_dereference().
