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-2018-19939 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-19939/ (Markdown: https://insights.sbomify.com/CVE-2018-19939/index.md)","id":"CVE-2018-19939","markdown":"https://insights.sbomify.com/CVE-2018-19939/index.md","name":"CVE-2018-19939","record":{"aliases":["GHSA-4v5p-wg3c-r4x4"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Xiaomi touchscreen driver","requires_auth":"none","summary":"A NULL pointer dereference in the Goodix touchscreen driver allows local attackers to cause a denial of service on Xiaomi devices.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mi_a2_lite_firmware","vendor":"mi"},{"product":"redmi_6_firmware","vendor":"mi"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The Goodix GT9xx touchscreen driver for custom Linux kernels on Xiaomi daisy-o-oss and daisy-p-oss as used in Mi A2 Lite and RedMi6 pro devices through 2018-08-27 has a NULL pointer dereference in kfree after a kmalloc failure in gtp_read_Color in drivers/input/touchscreen/gt917d/gt9xx.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Null dereference in n/a","id":"CVE-2018-19939","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Cleartext Storage of Sensitive Information in Cookies","id":"CVE-2018-19941"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2018-19937"},"products":["n/a"],"published":"2018-12-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"A NULL pointer dereference in the Goodix touchscreen driver allows local attackers to cause a denial of service on Xiaomi devices.","url":"https://insights.sbomify.com/CVE-2018-19939/"}
