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-2026-68256 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-68256/ (Markdown: https://insights.sbomify.com/CVE-2026-68256/index.md)","id":"CVE-2026-68256","markdown":"https://insights.sbomify.com/CVE-2026-68256/index.md","name":"CVE-2026-68256","record":{"aliases":["BELL-CVE-2026-68256","DEBIAN-CVE-2026-68256","GHSA-pvvr-9j3m-hvhg","UBUNTU-CVE-2026-68256"],"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":"none","summary":"A memory leak in the Linux kernel's AMD display driver can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: detect_link_and_local_sink: DP alt mode timeout path leaks prev_sink reference\n\nprev_sink is unconditionally retained via dc_sink_retain at function\n  entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT\n  returns false without releasing prev_sink.
