An issue was discovered in the Linux kernel through 5.18.9. A type
confusion bug in nft_set_elem_init (leading to a buffer overflow) could be
used by a local attacker to escalate privileges, a different vulnerability
than CVE-2022-32250. (The attacker can obtain root access, but must start
with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This
can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.
