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-2026-23061 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-23061/ (Markdown: https://insights.sbomify.com/CVE-2026-23061/index.md)","id":"CVE-2026-23061","markdown":"https://insights.sbomify.com/CVE-2026-23061/index.md","name":"CVE-2026-23061","record":{"aliases":["AZL-77124","BELL-CVE-2026-23061","DEBIAN-CVE-2026-23061","GHSA-84c2-7hw8-q83c","ROOT-OS-DEBIAN-11-CVE-2026-23061","ROOT-OS-DEBIAN-12-CVE-2026-23061","ROOT-OS-DEBIAN-13-CVE-2026-23061","ROOT-OS-UBUNTU-2204-CVE-2026-23061","ROOT-OS-UBUNTU-2404-CVE-2026-23061","UBUNTU-CVE-2026-23061"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A memory leak in the Kvaser USB CAN driver allows attackers to exhaust kernel memory, potentially causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: kvaser_usb: kvaser_usb_read_bulk_callback(): fix URB memory leak\n\nFix similar memory leak as in commit 7352e1d5932a (\"can: gs_usb:\ngs_usb_receive_bulk_callback(): fix URB memory leak\").\n\nIn kvaser_usb_set_{,data_}bittiming() -\u003e kvaser_usb_setup_rx_urbs(), the\nURBs for USB-in transfers are allocated, added to the dev-\u003erx_submitted\nanchor and submitted.
