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-2022-50874 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-2022-50874/ (Markdown: https://insights.sbomify.com/CVE-2022-50874/index.md)","id":"CVE-2022-50874","markdown":"https://insights.sbomify.com/CVE-2022-50874/index.md","name":"CVE-2022-50874","record":{"aliases":["DEBIAN-CVE-2022-50874","GHSA-9m95-7992-w3p3","UBUNTU-CVE-2022-50874"],"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 refcount leak in the Linux kernel RDMA driver allows local attackers to cause a denial of service by exhausting resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nRDMA/erdma: Fix refcount leak in erdma_mmap\n\nrdma_user_mmap_entry_get() take reference, we should release it when not\nneed anymore, add the missing rdma_user_mmap_entry_put() in the error\npath to fix it.","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":"RDMA/erdma: Fix refcount leak in erdma_mmap","id":"CVE-2022-50874","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop()","id":"CVE-2022-50875"},"packages":[],"prev":{"headline":"vdpa/vp_vdpa: fix kfree a wrong pointer in vp_vdpa_remove","id":"CVE-2022-50873"},"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 refcount leak in the Linux kernel RDMA driver allows local attackers to cause a denial of service by exhausting resources.","url":"https://insights.sbomify.com/CVE-2022-50874/"}
