An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-68188 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-68188/ (Markdown: https://insights.sbomify.com/CVE-2025-68188/index.md)","id":"CVE-2025-68188","markdown":"https://insights.sbomify.com/CVE-2025-68188/index.md","name":"CVE-2025-68188","record":{"aliases":["AZL-72538","BELL-CVE-2025-68188","DEBIAN-CVE-2025-68188","GHSA-3mc8-x7c9-wfw9","ROOT-OS-DEBIAN-11-CVE-2025-68188","ROOT-OS-DEBIAN-12-CVE-2025-68188","ROOT-OS-DEBIAN-13-CVE-2025-68188","ROOT-OS-UBUNTU-2204-CVE-2025-68188","ROOT-OS-UBUNTU-2404-CVE-2025-68188","UBUNTU-CVE-2025-68188"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel TCP stack allows remote attackers to cause denial of service or potentially execute code via crafted packets.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: use dst_dev_rcu() in tcp_fastopen_active_disable_ofo_check()\n\nUse RCU to avoid a pair of atomic operations and a potential\nUAF on dst_dev()-\u003eflags.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"tcp: use dst_dev_rcu() in tcp_fastopen_active_disable_ofo_check()","id":"CVE-2025-68188","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"drm/msm: Fix GEM free for imported dma-bufs","id":"CVE-2025-68189"},"packages":[],"prev":{"headline":"net: mdio: Check regmap pointer returned by device_node_to_regmap()","id":"CVE-2025-68187"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel TCP stack allows remote attackers to cause denial of service or potentially execute code via crafted packets.","url":"https://insights.sbomify.com/CVE-2025-68188/"}
