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-2024-56608 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-2024-56608/ (Markdown: https://insights.sbomify.com/CVE-2024-56608/index.md)","id":"CVE-2024-56608","markdown":"https://insights.sbomify.com/CVE-2024-56608/index.md","name":"CVE-2024-56608","record":{"aliases":["AZL-55205","BELL-CVE-2024-56608","DEBIAN-CVE-2024-56608","GHSA-h345-5w6p-mhwf","ROOT-OS-UBUNTU-2204-CVE-2024-56608","UBUNTU-CVE-2024-56608"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An out-of-bounds access in the AMD display driver can cause a kernel crash, requiring a patch to prevent denial of service.","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":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'\n\nAn issue was identified in the dcn21_link_encoder_create function where\nan out-of-bounds access could occur when the hpd_source index was used\nto reference the link_enc_hpd_regs array. This array has a fixed size\nand the index was not being checked against the array's bounds before\naccessing it.\n\nThis fix adds a conditional check to ensure that the hpd_source index is\nwithin the valid range of the link_enc_hpd_regs array.
