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-2026-46098 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-46098/ (Markdown: https://insights.sbomify.com/CVE-2026-46098/index.md)","id":"CVE-2026-46098","markdown":"https://insights.sbomify.com/CVE-2026-46098/index.md","name":"CVE-2026-46098","record":{"aliases":["AZL-88517","BELL-CVE-2026-46098","DEBIAN-CVE-2026-46098","GHSA-vfvp-r4j5-4q92","ROOT-OS-DEBIAN-11-CVE-2026-46098","ROOT-OS-DEBIAN-12-CVE-2026-46098","ROOT-OS-UBUNTU-2204-CVE-2026-46098","ROOT-OS-UBUNTU-2404-CVE-2026-46098","UBUNTU-CVE-2026-46098"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel CAIF network driver allows a local attacker to cause a system crash by triggering a double free during socket teardown.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: caif: clear client service pointer on teardown\n\n`caif_connect()` can tear down an existing client after remote shutdown by\ncalling `caif_disconnect_client()` followed by `caif_free_client()`.\n`caif_free_client()` releases the service layer referenced by\n`adap_layer-\u003edn`, but leaves that pointer stale.\n\nWhen the socket is later destroyed, `caif_sock_destructor()` calls\n`caif_free_client()` again and dereferences the freed service pointer.\n\nClear the client/service links before releasing the service object so\nrepeated teardown becomes harmless.","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":"net: caif: clear client service pointer on teardown","id":"CVE-2026-46098","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels","id":"CVE-2026-46099"},"packages":[],"prev":{"headline":"Input: edt-ft5x06 - fix use-after-free in debugfs teardown","id":"CVE-2026-46097"},"products":["Linux"],"published":"2026-05-27","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-06-14","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel CAIF network driver allows a local attacker to cause a system crash by triggering a double free during socket teardown.","url":"https://insights.sbomify.com/CVE-2026-46098/"}
