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-2020-36787 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-2020-36787/ (Markdown: https://insights.sbomify.com/CVE-2020-36787/index.md)","id":"CVE-2020-36787","markdown":"https://insights.sbomify.com/CVE-2020-36787/index.md","name":"CVE-2020-36787","record":{"aliases":["DEBIAN-CVE-2020-36787","GHSA-9hx5-6xv8-6w7c","UBUNTU-CVE-2020-36787"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A kernel driver bug causes random memory corruption and kernel panics on specific Aspeed SoCs, requiring a patch to fix clock handling logic.","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":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: aspeed: fix clock handling logic\n\nVideo engine uses eclk and vclk for its clock sources and its reset\ncontrol is coupled with eclk so the current clock enabling sequence works\nlike below.\n\n Enable eclk\n De-assert Video Engine reset\n 10ms delay\n Enable vclk\n\nIt introduces improper reset on the Video Engine hardware and eventually\nthe hardware generates unexpected DMA memory transfers that can corrupt\nmemory region in random and sporadic patterns.
