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-2022-50840 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-2022-50840/ (Markdown: https://insights.sbomify.com/CVE-2022-50840/index.md)","id":"CVE-2022-50840","markdown":"https://insights.sbomify.com/CVE-2022-50840/index.md","name":"CVE-2022-50840","record":{"aliases":["DEBIAN-CVE-2022-50840","GHSA-rwh2-wwjg-8c2j","UBUNTU-CVE-2022-50840"],"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":"none","summary":"A use-after-free vulnerability in the Linux kernel's snic driver allows local attackers to potentially execute 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\nscsi: snic: Fix possible UAF in snic_tgt_create()\n\nSmatch reports a warning as follows:\n\ndrivers/scsi/snic/snic_disc.c:307 snic_tgt_create() warn:\n  '\u0026tgt-\u003elist' not removed from list\n\nIf device_add() fails in snic_tgt_create(), tgt will be freed, but\ntgt-\u003elist will not be removed from snic-\u003edisc.tgt_list, then list traversal\nmay cause UAF.\n\nRemove from snic-\u003edisc.tgt_list before free().","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":"scsi: snic: Fix possible UAF in snic_tgt_create()","id":"CVE-2022-50840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":9,"next":{"headline":"fs/ntfs3: Add overflow check for attribute size","id":"CVE-2022-50841"},"packages":[],"prev":{"headline":"jbd2: fix potential buffer head reference count leak","id":"CVE-2022-50839"},"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's snic driver allows local attackers to potentially execute code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2022-50840/"}
