    CVE-2022-32250:
    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create
    user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to
    a use-after-free.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.
