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 CVE-2026-12166 in the wild and no public exploit code.\n\nAffected product: Little Orbit GameFirst Anti-Cheat. No package-level version data is available, so check the vendor advisory linked from the reference page.\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/CVE-2026-12166/ (Markdown: https://insights.sbomify.com/CVE-2026-12166/index.md)","id":"CVE-2026-12166","markdown":"https://insights.sbomify.com/CVE-2026-12166/index.md","name":"CVE-2026-12166","record":{"aliases":["GHSA-rp8q-7vcj-j55j"],"analysis":{"component_type":"operating_system","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Anti-Cheat Driver","requires_auth":"low_privilege","summary":"A local attacker can cause a system crash in the GFAC anti-cheat driver via a NULL pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"A NULL pointer dereference vulnerability for driver `GFAC_Sys_x64.sys` in Little Orbit GFAC allows a local attacker to cause a denial of service via crafted requests that trigger a system crash.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-02","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-02T08:33:35Z","kind":"github_poc","ref":"https://github.com/FzRsLLaSheR/CVE-2026-12166_CVE-2026-12167_CVE-2026-12168","stars":1,"title":null}],"tier":"poc_unverified"},"has_fix":null,"headline":"CVE-2026-12166","id":"CVE-2026-12166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"CVE-2026-12167","id":"CVE-2026-12167"},"packages":[],"prev":{"headline":"Contest Gallery \u003c= 30.0.2 - Authenticated (Author+) Privilege Escalation via 'RegistryUserRole' Parameter","id":"CVE-2026-12165"},"products":["GameFirst Anti-Cheat"],"published":"2026-07-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-02","vendors":["Little Orbit"]},"summary":"A local attacker can cause a system crash in the GFAC anti-cheat driver via a NULL pointer dereference.","url":"https://insights.sbomify.com/CVE-2026-12166/"}
