Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-50241 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-2022-50241/ (Markdown: https://insights.sbomify.com/CVE-2022-50241/index.md)","id":"CVE-2022-50241","markdown":"https://insights.sbomify.com/CVE-2022-50241/index.md","name":"CVE-2022-50241","record":{"aliases":["DEBIAN-CVE-2022-50241","GHSA-wc22-wv2f-7f64","UBUNTU-CVE-2022-50241"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's NFSD allows attackers to cause denial of service or potentially execute code via inter-server copy operations.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFSD: fix use-after-free on source server when doing inter-server copy\n\nUse-after-free occurred when the laundromat tried to free expired\ncpntf_state entry on the s2s_cp_stateids list after inter-server\ncopy completed. The sc_cp_list that the expired copy state was\ninserted on was already freed.\n\nWhen COPY completes, the Linux client normally sends LOCKU(lock_state x),\nFREE_STATEID(lock_state x) and CLOSE(open_state y) to the source server.\nThe nfs4_put_stid call from nfsd4_free_stateid cleans up the copy state\nfrom the s2s_cp_stateids list before freeing the lock state's stid.\n\nHowever, sometimes the CLOSE was sent before the FREE_STATEID request.\nWhen this happens, the nfsd4_close_open_stateid call from nfsd4_close\nfrees all lock states on its st_locks list without cleaning up the copy\nstate on the sc_cp_list list. When the time the FREE_STATEID arrives the\nserver returns BAD_STATEID since the lock state was freed. This causes\nthe use-after-free error to occur when the laundromat tries to free\nthe expired cpntf_state.\n\nThis patch adds a call to nfs4_free_cpntf_statelist in\nnfsd4_close_open_stateid to clean up the copy state before calling\nfree_ol_stateid_reaplist to free the lock state's stid on the reaplist.","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":"NFSD: fix use-after-free on source server when doing inter-server copy","id":"CVE-2022-50241","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"drivers: net: qlcnic: Fix potential memory leak in qlcnic_sriov_init()","id":"CVE-2022-50242"},"packages":[],"prev":{"headline":"android: binder: stop saving a pointer to the VMA","id":"CVE-2022-50240"},"products":["Linux"],"published":"2025-09-15","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's NFSD allows attackers to cause denial of service or potentially execute code via inter-server copy operations.","url":"https://insights.sbomify.com/CVE-2022-50241/"}
