In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables
when processing batch requests can be abused to perform arbitrary read and
write operations on kernel memory. Unprivileged local users can obtain root
privileges. This occurs because anonymous sets are mishandled.

Notes

Author Note
cascardo requires CAP_NET_ADMIN, however this can be done within a new user namespace and network namespace - so can be mitigated by disabling unprivileged user namespaces.
