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-2025-68343 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-2025-68343/ (Markdown: https://insights.sbomify.com/CVE-2025-68343/index.md)","id":"CVE-2025-68343","markdown":"https://insights.sbomify.com/CVE-2025-68343/index.md","name":"CVE-2025-68343","record":{"aliases":["AZL-72995","BELL-CVE-2025-68343","DEBIAN-CVE-2025-68343","GHSA-mr5c-58ff-m852","ROOT-OS-DEBIAN-11-CVE-2025-68343","ROOT-OS-DEBIAN-12-CVE-2025-68343","ROOT-OS-DEBIAN-13-CVE-2025-68343","ROOT-OS-UBUNTU-2204-CVE-2025-68343","ROOT-OS-UBUNTU-2404-CVE-2025-68343","UBUNTU-CVE-2025-68343"],"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":"none","summary":"A missing length check in the gs_usb CAN driver allows a local attacker to cause a kernel crash via a short USB packet.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\ncan: gs_usb: gs_usb_receive_bulk_callback(): check actual_length before accessing header\n\nThe driver expects to receive a struct gs_host_frame in\ngs_usb_receive_bulk_callback().\n\nUse struct_group to describe the header of the struct gs_host_frame and\ncheck that we have at least received the header before accessing any\nmembers of it.\n\nTo resubmit the URB, do not dereference the pointer chain\n\"dev-\u003eparent-\u003ehf_size_rx\" but use \"parent-\u003ehf_size_rx\" instead.
