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-2022-4994 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-2022-4994/ (Markdown: https://insights.sbomify.com/CVE-2022-4994/index.md)","id":"CVE-2022-4994","markdown":"https://insights.sbomify.com/CVE-2022-4994/index.md","name":"CVE-2022-4994","record":{"aliases":["DEBIAN-CVE-2022-4994","GHSA-p8vm-xf6w-g5jx","UBUNTU-CVE-2022-4994"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"high_privilege","summary":"A refactoring change in the Linux kernel KVM module that has no functional impact or security vulnerability.","user_interaction":"not_required","vuln_class":"other"},"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\nKVM: x86: wean fast IN from emulator_pio_in\n\nUse __emulator_pio_in() directly for fast PIO instead of bouncing through\nemulator_pio_in() now that __emulator_pio_in() fills \"val\" when handling\nin-kernel PIO.  vcpu-\u003earch.pio.count is guaranteed to be '0', so this a\npure nop.\n\nemulator_pio_in_emulated is now the last caller of emulator_pio_in.\n\nNo functional change intended.","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":"KVM: x86: wean fast IN from emulator_pio_in","id":"CVE-2022-4994","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Weaver E-cology 9.0 File Upload RCE via uploaderOperate.jsp","id":"CVE-2022-4995"},"packages":[],"prev":{"headline":"HTML::FormHandler versions before 0.410000 for Perl allow attacker selected method dispatch and resource exhaustion because _apply_actions a","id":"CVE-2022-4993"},"products":["Linux"],"published":"2026-07-30","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":"2026-07-30","vendors":["Linux"]},"summary":"A refactoring change in the Linux kernel KVM module that has no functional impact or security vulnerability.","url":"https://insights.sbomify.com/CVE-2022-4994/"}
