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-2022-50640 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-2022-50640/ (Markdown: https://insights.sbomify.com/CVE-2022-50640/index.md)","id":"CVE-2022-50640","markdown":"https://insights.sbomify.com/CVE-2022-50640/index.md","name":"CVE-2022-50640","record":{"aliases":["DEBIAN-CVE-2022-50640","GHSA-4w99-c287-2jvj","UBUNTU-CVE-2022-50640"],"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":"none","summary":"A use-after-free vulnerability in the Linux kernel MMC core allows local attackers to cause a kernel panic by removing a non-standard SDIO card.","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\nmmc: core: Fix kernel panic when remove non-standard SDIO card\n\nSDIO tuple is only allocated for standard SDIO card, especially it causes\nmemory corruption issues when the non-standard SDIO card has removed, which\nis because the card device's reference counter does not increase for it at\nsdio_init_func(), but all SDIO card device reference counter gets decreased\nat sdio_release_func().","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":"mmc: core: Fix kernel panic when remove non-standard SDIO card","id":"CVE-2022-50640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":8,"next":{"headline":"HSI: omap_ssi: Fix refcount leak in ssi_probe","id":"CVE-2022-50641"},"packages":[],"prev":{"headline":"io-wq: Fix memory leak in worker creation","id":"CVE-2022-50639"},"products":["Linux"],"published":"2025-12-09","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 MMC core allows local attackers to cause a kernel panic by removing a non-standard SDIO card.","url":"https://insights.sbomify.com/CVE-2022-50640/"}
