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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-843"],"references":["http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html","http://packetstormsecurity.com/files/168543/Netfilter-nft_set_elem_init-Heap-Overflow-Privilege-Escalation.html","http://www.openwall.com/lists/oss-security/2022/07/05/1","http://www.openwall.com/lists/oss-security/2022/08/06/5","https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=7e6bc1f6cabcd30aba0b11219d8e01b952eacbb6"],"products":["canonical:ubuntu_linux","debian:debian_linux","linux:linux_kernel","netapp:h300s_firmware","netapp:h410c_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-34918","score":0.05451,"percentile":0.92678,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
