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-2022-49659 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-2022-49659/ (Markdown: https://insights.sbomify.com/CVE-2022-49659/index.md)","id":"CVE-2022-49659","markdown":"https://insights.sbomify.com/CVE-2022-49659/index.md","name":"CVE-2022-49659","record":{"aliases":["DEBIAN-CVE-2022-49659","GHSA-2cw3-cw9w-9ww5","UBUNTU-CVE-2022-49659"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CAN driver","requires_auth":"low_privilege","summary":"The Linux kernel CAN driver mishandles 16-bit timestamps, causing potential logic errors in RX-offload processing.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: m_can: m_can_{read_fifo,echo_tx_event}(): shift timestamp to full 32 bits\n\nIn commit 1be37d3b0414 (\"can: m_can: fix periph RX path: use\nrx-offload to ensure skbs are sent from softirq context\") the RX path\nfor peripheral devices was switched to RX-offload.\n\nReceived CAN frames are pushed to RX-offload together with a\ntimestamp.
