Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-26076 and fix it if it is affected.\n\nWhat it is: CVE-2023-26076 is a high-severity memory corruption vulnerability in Samsung Exynos 1280 Firmware, published on 13 Mar 2023. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26076 in the wild and no public exploit code.\n\nAffected product: Samsung Exynos 1280 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-2023-26076/ (Markdown: https://insights.sbomify.com/CVE-2023-26076/index.md)","id":"CVE-2023-26076","markdown":"https://insights.sbomify.com/CVE-2023-26076/index.md","name":"CVE-2023-26076","record":{"aliases":["A-269656642","GHSA-64g2-hhj4-h788","PUB-A-269656642"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Samsung Exynos modem","requires_auth":"low_privilege","summary":"An intra-object overflow in Samsung Exynos 5G modem firmware allows attackers to execute arbitrary code or escalate privileges via malformed messages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exynos_1280_firmware","vendor":"samsung"},{"product":"exynos_2200_firmware","vendor":"samsung"},{"product":"exynos_auto_t5123_firmware","vendor":"samsung"},{"product":"exynos_modem_5123_firmware","vendor":"samsung"},{"product":"exynos_modem_5300_firmware","vendor":"samsung"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:N/A:H/C:L/I:L/PR:L/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"An issue was discovered in Samsung Mobile Chipset and Baseband Modem Chipset for Exynos 1280, Exynos 2200, Exynos Modem 5123, Exynos Modem 5300, and Exynos Auto T5123.
