An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74737 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-2026-74737/ (Markdown: https://insights.sbomify.com/CVE-2026-74737/index.md)","id":"CVE-2026-74737","markdown":"https://insights.sbomify.com/CVE-2026-74737/index.md","name":"CVE-2026-74737","record":{"aliases":["AZL-97797","BELL-CVE-2026-74737","DEBIAN-CVE-2026-74737","GHSA-582m-3r7c-4438","UBUNTU-CVE-2026-74737"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A flaw in the TI AM65 CPSW driver allows out-of-bounds memory access due to incorrect port ID extraction, leading to kernel crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\nnet: ethernet: ti: am65-cpsw-nuss: Fix port_id extraction from SRC TAG\n\nOn the packet reception path, the ID of the MAC Port on which the packet\nwas received, is embedded in the RX DMA Descriptor's metadata.
