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-2022-50843 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-2022-50843/ (Markdown: https://insights.sbomify.com/CVE-2022-50843/index.md)","id":"CVE-2022-50843","markdown":"https://insights.sbomify.com/CVE-2022-50843/index.md","name":"CVE-2022-50843","record":{"aliases":["DEBIAN-CVE-2022-50843","GHSA-f4xq-gq7q-8jfg","UBUNTU-CVE-2022-50843"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A use-after-free vulnerability in the Linux kernel dm clone module allows local attackers with high privileges to execute arbitrary code or escalate privileges.","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\ndm clone: Fix UAF in clone_dtr()\n\nDm_clone also has the same UAF problem when dm_resume()\nand dm_destroy() are concurrent.\n\nTherefore, cancelling timer again in clone_dtr().","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":"dm clone: Fix UAF in clone_dtr()","id":"CVE-2022-50843","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":6,"next":{"headline":"drm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callback","id":"CVE-2022-50844"},"packages":[],"prev":{"headline":"drm/virtio: Check whether transferred 2D BO is shmem","id":"CVE-2022-50842"},"products":["Linux"],"published":"2025-12-30","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":"2026-05-11","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel dm clone module allows local attackers with high privileges to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2022-50843/"}
