CVE-2022-49672

CVE-2022-49672 refers to a race condition in the Linux kernel’s network/tun path: when destroying a tunNAPI object, the NAPI in the tun_file struct can be destroyed before the netdev, requiring explicit deletion of the NAPI. Syzbot observed this race as the queue was detached, enabling a potentia...
