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-2023-28577 in the wild and no public exploit code.\n\nAffected product: Qualcomm Fastconnect 6800 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-2023-28577/ (Markdown: https://insights.sbomify.com/CVE-2023-28577/index.md)","id":"CVE-2023-28577","markdown":"https://insights.sbomify.com/CVE-2023-28577/index.md","name":"CVE-2023-28577","record":{"aliases":["3489559","A-283319714","GHSA-rjh6-h795-3mrj","PUB-A-283319714"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Qualcomm Snapdragon","requires_auth":"high_privilege","summary":"A race condition in Qualcomm Snapdragon drivers allows attackers to trigger a use-after-free, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"fastconnect_6800_firmware","vendor":"qualcomm"},{"product":"fastconnect_6900_firmware","vendor":"qualcomm"},{"product":"fastconnect_7800_firmware","vendor":"qualcomm"},{"product":"qca6391_firmware","vendor":"qualcomm"},{"product":"qca6426_firmware","vendor":"qualcomm"},{"product":"qca6436_firmware","vendor":"qualcomm"},{"product":"qcn9074_firmware","vendor":"qualcomm"},{"product":"qcs410_firmware","vendor":"qualcomm"},{"product":"qcs610_firmware","vendor":"qualcomm"},{"product":"sd865_5g_firmware","vendor":"qualcomm"},{"product":"snapdragon_865\\+_5g_firmware","vendor":"qualcomm"},{"product":"snapdragon_865_5g_firmware","vendor":"qualcomm"},{"product":"snapdragon_870_5g_firmware","vendor":"qualcomm"},{"product":"snapdragon_8_gen_1_firmware","vendor":"qualcomm"},{"product":"snapdragon_x55_5g_firmware","vendor":"qualcomm"},{"product":"snapdragon_xr2_5g_firmware","vendor":"qualcomm"},{"product":"sw5100_firmware","vendor":"qualcomm"},{"product":"sw5100p_firmware","vendor":"qualcomm"},{"product":"sxr2130_firmware","vendor":"qualcomm"},{"product":"wcd9341_firmware","vendor":"qualcomm"},{"product":"wcd9370_firmware","vendor":"qualcomm"},{"product":"wcd9380_firmware","vendor":"qualcomm"},{"product":"wcn3660b_firmware","vendor":"qualcomm"},{"product":"wcn3680b_firmware","vendor":"qualcomm"},{"product":"wcn3950_firmware","vendor":"qualcomm"},{"product":"wcn3980_firmware","vendor":"qualcomm"},{"product":"wcn3988_firmware","vendor":"qualcomm"},{"product":"wsa8810_firmware","vendor":"qualcomm"},{"product":"wsa8815_firmware","vendor":"qualcomm"},{"product":"wsa8830_firmware","vendor":"qualcomm"},{"product":"wsa8835_firmware","vendor":"qualcomm"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the function call related to CAM_REQ_MGR_RELEASE_BUF there is no check if the buffer is being used.
