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-2026-74410 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-2026-74410/ (Markdown: https://insights.sbomify.com/CVE-2026-74410/index.md)","id":"CVE-2026-74410","markdown":"https://insights.sbomify.com/CVE-2026-74410/index.md","name":"CVE-2026-74410","record":{"aliases":["BELL-CVE-2026-74410","DEBIAN-CVE-2026-74410","GHSA-xfh3-hf97-85m6","UBUNTU-CVE-2026-74410"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"An out-of-bounds read in the rtw88 PCIe WiFi driver allows attackers to read memory or cause a crash via crafted firmware descriptors.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer\n\nIn rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit\ndescriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both\nfirmware-controlled).
