It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-jr8j-2jhp-m67v in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/siderolabs/talos (Go): affected all versions; fixed in 1.2.0\n- github.com/siderolabs/talos (Go): affected all versions; fixed in 1.2.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-jr8j-2jhp-m67v/ (Markdown: https://insights.sbomify.com/GHSA-jr8j-2jhp-m67v/index.md)","id":"GHSA-jr8j-2jhp-m67v","markdown":"https://insights.sbomify.com/GHSA-jr8j-2jhp-m67v/index.md","name":"GHSA-jr8j-2jhp-m67v","record":{"aliases":[],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can cause a denial of service in the Linux kernel by binding to an already bound nftables chain.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### 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).
