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-2021-35091 in the wild and no public exploit code.\n\nAffected product: Qualcomm Sd 8 Gen1 5g 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-2021-35091/ (Markdown: https://insights.sbomify.com/CVE-2021-35091/index.md)","id":"CVE-2021-35091","markdown":"https://insights.sbomify.com/CVE-2021-35091/index.md","name":"CVE-2021-35091","record":{"aliases":["3008877","A-204905109","ASB-A-204905109","GHSA-54q7-86rf-qx6x"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Qualcomm Snapdragon firmware","requires_auth":"none","summary":"An out-of-bounds read in Qualcomm Snapdragon firmware allows attackers to read memory or cause a denial of service via improper typecasting during page fault handling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"sd_8_gen1_5g_firmware","vendor":"qualcomm"},{"product":"wcd9380_firmware","vendor":"qualcomm"},{"product":"wcn6855_firmware","vendor":"qualcomm"},{"product":"wcn6856_firmware","vendor":"qualcomm"},{"product":"wsa8830_firmware","vendor":"qualcomm"},{"product":"wsa8835_firmware","vendor":"qualcomm"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-704","name":"Incorrect Type Conversion or Cast"}],"description":"Possible out of bounds read due to improper typecasting while handling page fault for global memory in Snapdragon Connectivity, Snapdragon Mobile","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":"Memory corruption in Snapdragon Connectivity, Snapdragon Mobile","id":"CVE-2021-35091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qualcomm:sd_8_gen1_5g_firmware","products":["qualcomm:sd_8_gen1_5g_firmware","qualcomm:wcd9380_firmware","qualcomm:wcn6855_firmware","qualcomm:wcn6856_firmware","qualcomm:wsa8830_firmware","qualcomm:wsa8835_firmware"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice \u0026 Music","id":"CVE-2021-35092"},"packages":[],"prev":{"headline":"Race condition in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Industrial IOT, Snapdragon Mobile","id":"CVE-2021-35090"},"products":["Snapdragon Connectivity, Snapdragon Mobile"],"published":"2022-06-14","related":[{"cvss_score":8.4,"headline":"Use after free in Snapdragon Mobile","id":"CVE-2022-25723","kev_date_added":null,"published":"2022-10-17"},{"cvss_score":8.4,"headline":"Use after free in Snapdragon Mobile","id":"CVE-2022-22077","kev_date_added":null,"published":"2022-10-12"},{"cvss_score":8.4,"headline":"Use after free in Snapdragon Connectivity, Snapdragon Mobile","id":"CVE-2022-25693","kev_date_added":null,"published":"2022-09-16"},{"cvss_score":8.1,"headline":"Memory corruption in Snapdragon Connectivity, Snapdragon Mobile","id":"CVE-2021-35110","kev_date_added":null,"published":"2022-04-01"},{"cvss_score":7.8,"headline":"Memory corruption in Snapdragon Mobile","id":"CVE-2022-33217","kev_date_added":null,"published":"2022-10-17"},{"cvss_score":6.8,"headline":"Buffer over-read in Trusted Execution Environment","id":"CVE-2022-33221","kev_date_added":null,"published":"2023-02-09"}],"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":"2024-08-04","vendors":["Qualcomm, Inc."]},"summary":"An out-of-bounds read in Qualcomm Snapdragon firmware allows attackers to read memory or cause a denial of service via improper typecasting during page fault handling.","url":"https://insights.sbomify.com/CVE-2021-35091/"}
