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-2022-50852 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-2022-50852/ (Markdown: https://insights.sbomify.com/CVE-2022-50852/index.md)","id":"CVE-2022-50852","markdown":"https://insights.sbomify.com/CVE-2022-50852/index.md","name":"CVE-2022-50852","record":{"aliases":["DEBIAN-CVE-2022-50852","GHSA-78hp-5r4f-844r","UBUNTU-CVE-2022-50852"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free flaw in the Linux kernel mt7921 Wi-Fi driver allows local attackers to execute arbitrary code or cause a system crash.","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\nwifi: mt76: mt7921: fix use after free in mt7921_acpi_read()\n\nDon't dereference \"sar_root\" after it has been freed.","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":"wifi: mt76: mt7921: fix use after free in mt7921_acpi_read()","id":"CVE-2022-50852","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"NFSv4: Fix a credential leak in _nfs4_discover_trunking()","id":"CVE-2022-50853"},"packages":[],"prev":{"headline":"vhost_vdpa: fix the crash in unmap a large memory","id":"CVE-2022-50851"},"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 use-after-free flaw in the Linux kernel mt7921 Wi-Fi driver allows local attackers to execute arbitrary code or cause a system crash.","url":"https://insights.sbomify.com/CVE-2022-50852/"}
