- In the Linux kernel, the following vulnerability has been resolved: net/xen-netback: prevent UAF in
xenvif_flush_hash() During the list_for_each_entry_rcu iteration call of xenvif_flush_hash, kfree_rcu does
not exist inside the rcu read critical section, so if kfree_rcu is called when the rcu grace period ends
during the iteration, UAF occurs when accessing head->next after the entry becomes free. Therefore, to
solve this, you need to change it to list_for_each_entry_safe. (CVE-2024-49936)
