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-2024-56539 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-56539/ (Markdown: https://insights.sbomify.com/CVE-2024-56539/index.md)","id":"CVE-2024-56539","markdown":"https://insights.sbomify.com/CVE-2024-56539/index.md","name":"CVE-2024-56539","record":{"aliases":["BELL-CVE-2024-56539","DEBIAN-CVE-2024-56539","GHSA-3598-6xhq-v9q3","UBUNTU-CVE-2024-56539"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"low_privilege","summary":"A memory corruption issue in the Linux kernel's mwifiex WiFi driver can cause a system crash or warning during network scanning.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_config_scan()\n\nReplace one-element array with a flexible-array member in `struct\nmwifiex_ie_types_wildcard_ssid_params` to fix the following warning\non a MT8173 Chromebook (mt8173-elm-hana):\n\n[  356.775250] ------------[ cut here ]------------\n[  356.784543] memcpy: detected field-spanning write (size 6) of single field \"wildcard_ssid_tlv-\u003essid\" at drivers/net/wireless/marvell/mwifiex/scan.c:904 (size 1)\n[  356.813403] WARNING: CPU: 3 PID: 742 at drivers/net/wireless/marvell/mwifiex/scan.c:904 mwifiex_scan_networks+0x4fc/0xf28 [mwifiex]\n\nThe \"(size 6)\" above is exactly the length of the SSID of the network\nthis device was connected to.
