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-2026-64497 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-2026-64497/ (Markdown: https://insights.sbomify.com/CVE-2026-64497/index.md)","id":"CVE-2026-64497","markdown":"https://insights.sbomify.com/CVE-2026-64497/index.md","name":"CVE-2026-64497","record":{"aliases":["BELL-CVE-2026-64497","DEBIAN-CVE-2026-64497","GHSA-mrh8-mp34-58pv","ROOT-OS-UBUNTU-2204-CVE-2026-64497","UBUNTU-CVE-2026-64497"],"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 driver","requires_auth":"none","summary":"A sign-extension bug in the Linux kernel SCD30 sensor driver can corrupt data, potentially leading to information disclosure or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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\niio: chemical: scd30: Cleanup initializations and fix sign-extension bug\n\nInclude linux/bitfield.h for FIELD_GET().\n\nCreate new macros for bit manipulation in combination with manual bit\nmanipulation being replaced with FIELD_GET().\n\nThe current variable declaration and initializations are barely readable\nand use comma separations across multiple lines.
