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-2024-56616 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-2024-56616/ (Markdown: https://insights.sbomify.com/CVE-2024-56616/index.md)","id":"CVE-2024-56616","markdown":"https://insights.sbomify.com/CVE-2024-56616/index.md","name":"CVE-2024-56616","record":{"aliases":["BELL-CVE-2024-56616","DEBIAN-CVE-2024-56616","GHSA-ghmx-w25c-9jmr","UBUNTU-CVE-2024-56616"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing length check in the Linux kernel's DisplayPort MST driver allows a malicious device to trigger memory corruption, potentially causing a crash or code execution.","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":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/dp_mst: Fix MST sideband message body length check\n\nFix the MST sideband message body length check, which must be at least 1\nbyte accounting for the message body CRC (aka message data CRC) at the\nend of the message.\n\nThis fixes a case where an MST branch device returns a header with a\ncorrect header CRC (indicating a correctly received body length), with\nthe body length being incorrectly set to 0.
