It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-11857 and fix it if it is affected.\n\nWhat it is: CVE-2018-11857 is a high-severity memory corruption vulnerability in Qualcomm Sd 835 Firmware, published on 29 Oct 2018. 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-2018-11857 in the wild and no public exploit code.\n\nAffected product: Qualcomm Sd 835 Firmware. 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-2018-11857/ (Markdown: https://insights.sbomify.com/CVE-2018-11857/index.md)","id":"CVE-2018-11857","markdown":"https://insights.sbomify.com/CVE-2018-11857/index.md","name":"CVE-2018-11857","record":{"aliases":["GHSA-22qr-vprq-hjw2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Snapdragon Mobile","requires_auth":"low_privilege","summary":"Improper input validation in the WLAN module allows buffer overflows, potentially enabling code execution or privilege escalation on affected mobile devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"sd_835_firmware","vendor":"qualcomm"},{"product":"sd_845_firmware","vendor":"qualcomm"},{"product":"sd_850_firmware","vendor":"qualcomm"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper input validation in WLAN encrypt/decrypt module can lead to a buffer copy in Snapdragon Mobile in version SD 835, SD 845, SD 850","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":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11857","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qualcomm:sd_835_firmware","products":["qualcomm:sd_835_firmware","qualcomm:sd_845_firmware","qualcomm:sd_850_firmware"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11858"},"packages":[],"prev":{"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11856"},"products":["Snapdragon Mobile"],"published":"2018-10-29","related":[{"cvss_score":9.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2016-10460","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":7.8,"headline":"Null dereference in Snapdragon Mobile","id":"CVE-2018-5870","kev_date_added":null,"published":"2018-11-28"},{"cvss_score":7.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11856","kev_date_added":null,"published":"2018-10-29"},{"cvss_score":7.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11858","kev_date_added":null,"published":"2018-10-29"},{"cvss_score":7.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11874","kev_date_added":null,"published":"2018-10-29"},{"cvss_score":7.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2018-11876","kev_date_added":null,"published":"2018-10-29"}],"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":["Qualcomm, Inc."]},"summary":"Improper input validation in the WLAN module allows buffer overflows, potentially enabling code execution or privilege escalation on affected mobile devices.","url":"https://insights.sbomify.com/CVE-2018-11857/"}
