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-2026-90035 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-2026-90035/ (Markdown: https://insights.sbomify.com/CVE-2026-90035/index.md)","id":"CVE-2026-90035","markdown":"https://insights.sbomify.com/CVE-2026-90035/index.md","name":"CVE-2026-90035","record":{"aliases":["AZL-101187","BELL-CVE-2026-90035","DEBIAN-CVE-2026-90035","GHSA-535w-j2qq-gp7f","UBUNTU-CVE-2026-90035"],"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 malicious USB4/DPIA device can trigger a division by zero in the Linux kernel, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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: fix division by zero in get_estimated_bw()\n\nget_estimated_bw() divides by link-\u003edpia_bw_alloc_config.bw_granularity,\nwhich is zeroed by reset_bw_alloc_struct() and only populated once\nDP_TUNNELING_BW_ALLOC_CAP_CHANGED has been handled.\n\nlink_dp_dpia_handle_bw_alloc_status(), the DPCD interrupt handler,\ncalls get_estimated_bw() whenever DP_TUNNELING_ESTIMATED_BW_CHANGED\nis set, independently of whether DP_TUNNELING_BW_ALLOC_CAP_CHANGED\nhas ever fired for that link.
