{"id":"GHSA-jr8j-2jhp-m67v","summary":"nftables binding to an already bound chain","details":"### Impact\nAn issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel. A denial of service can occur upon binding to an already bound chain.\n\nAffected by this vulnerability is the function nft_verdict_init of the file net/netfilter/nf_tables_api.c. The manipulation with an unknown input leads to a denial of service vulnerability. The program does not release or incorrectly releases a resource before it is made available for re-use.\n\n### Patches\nThe fix has been backported to [5.15.64](https://www.linuxkernelcves.com/cves/CVE-2022-39190) version of the upstream Linux kernel (5.15 is the upstream Kernel long term version Talos ships with). Talos \u003e= v1.2.0 is shipped with Linux Kernel 5.15.64 fixing the above issue.\n\n### Workarounds\nIt's recommended to upgrade\n\n### References\n- https://www.sesin.at/2022/09/02/cve-2022-39190-linux-kernel-up-to-5-19-5-nf_tables_api-c-nft_verdict_init-denial-of-service/\n- https://nvd.nist.gov/vuln/detail/CVE-2022-39190\n\n### For more information\n- Email us at [security@siderolabs.com](mailto:security@siderolabs.com)","modified":"2022-09-16T17:17:56Z","published":"2022-09-16T17:17:56Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-09-16T17:17:56Z","nvd_published_at":null,"cwe_ids":[]},"references":[{"type":"WEB","url":"https://github.com/siderolabs/talos/security/advisories/GHSA-jr8j-2jhp-m67v"},{"type":"PACKAGE","url":"https://github.com/siderolabs/talos"}],"affected":[{"package":{"name":"github.com/siderolabs/talos","ecosystem":"Go","purl":"pkg:golang/github.com/siderolabs/talos"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.2.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-jr8j-2jhp-m67v/GHSA-jr8j-2jhp-m67v.json"}}],"schema_version":"1.9.0"}
