An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-36648 in the wild and no public exploit code.\n\nAffected product: Qemu Qemu. 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-2022-36648/ (Markdown: https://insights.sbomify.com/CVE-2022-36648/index.md)","id":"CVE-2022-36648","markdown":"https://insights.sbomify.com/CVE-2022-36648/index.md","name":"CVE-2022-36648","record":{"aliases":["AZL-28069","AZL-35162","DEBIAN-CVE-2022-36648","GHSA-4xpq-qfh7-r9h2","OESA-2026-3046","OESA-2026-3101","OESA-2026-3102","OESA-2026-3103"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"QEMU emulator","requires_auth":"none","summary":"A null pointer dereference in QEMU's rocker device model allows guest users to crash the host or potentially execute code, though validity is disputed.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"qemu","vendor":"qemu"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS.
