It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-9500 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-2019-9500/ (Markdown: https://insights.sbomify.com/CVE-2019-9500/index.md)","id":"CVE-2019-9500","markdown":"https://insights.sbomify.com/CVE-2019-9500/index.md","name":"CVE-2019-9500","record":{"aliases":["DEBIAN-CVE-2019-9500","GHSA-6jhq-h73f-x439","RHSA-2019:2945","RHSA-2019:4168","RHSA-2019:4171","UBUNTU-CVE-2019-9500"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Broadcom WiFi driver","requires_auth":"none","summary":"A heap buffer overflow in the Broadcom brcmfmac WiFi driver allows remote code execution or denial of service if Wake-on-LAN is enabled.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"brcmfmac_driver","vendor":"broadcom"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow.

This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
