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-2022-50742 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-2022-50742/ (Markdown: https://insights.sbomify.com/CVE-2022-50742/index.md)","id":"CVE-2022-50742","markdown":"https://insights.sbomify.com/CVE-2022-50742/index.md","name":"CVE-2022-50742","record":{"aliases":["DEBIAN-CVE-2022-50742","GHSA-7fvc-c9hj-7pgf","UBUNTU-CVE-2022-50742"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A refcount leak in the Linux kernel ocxl 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\nmisc: ocxl: fix possible refcount leak in afu_ioctl()\n\neventfd_ctx_put need to be called to put the refcount that gotten by\neventfd_ctx_fdget when ocxl_irq_set_handler fails.","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":"misc: ocxl: fix possible refcount leak in afu_ioctl()","id":"CVE-2022-50742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":6,"next":{"headline":"erofs: Fix pcluster memleak when its block address is zero","id":"CVE-2022-50743"},"packages":[],"prev":{"headline":"media: imx-jpeg: Disable useless interrupt to avoid kernel panic","id":"CVE-2022-50741"},"products":["Linux"],"published":"2025-12-24","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 ocxl driver allows local attackers to cause a denial of service by exhausting resources.","url":"https://insights.sbomify.com/CVE-2022-50742/"}
