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-2022-50858 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-2022-50858/ (Markdown: https://insights.sbomify.com/CVE-2022-50858/index.md)","id":"CVE-2022-50858","markdown":"https://insights.sbomify.com/CVE-2022-50858/index.md","name":"CVE-2022-50858","record":{"aliases":["DEBIAN-CVE-2022-50858","GHSA-m3wv-5mmv-w433","UBUNTU-CVE-2022-50858"],"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":"none","summary":"A missing return value check in the Alcor MMC driver can cause a kernel crash, leading to denial of service for local attackers.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: alcor: fix return value check of mmc_add_host()\n\nmmc_add_host() may return error, if we ignore its return value, the memory\nthat allocated in mmc_alloc_host() will be leaked and it will lead a kernel\ncrash because of deleting not added device in the remove path.\n\nSo fix this by checking the return value and calling mmc_free_host() in the\nerror path.","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: alcor: fix return value check of mmc_add_host()","id":"CVE-2022-50858","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":6,"next":{"headline":"cifs: Fix the error length of VALIDATE_NEGOTIATE_INFO message","id":"CVE-2022-50859"},"packages":[],"prev":{"headline":"rapidio: rio: fix possible name leak in rio_register_mport()","id":"CVE-2022-50857"},"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 missing return value check in the Alcor MMC driver can cause a kernel crash, leading to denial of service for local attackers.","url":"https://insights.sbomify.com/CVE-2022-50858/"}
