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-2022-49227 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-2022-49227/ (Markdown: https://insights.sbomify.com/CVE-2022-49227/index.md)","id":"CVE-2022-49227","markdown":"https://insights.sbomify.com/CVE-2022-49227/index.md","name":"CVE-2022-49227","record":{"aliases":["DEBIAN-CVE-2022-49227","GHSA-vv5g-r8mg-xvc2","UBUNTU-CVE-2022-49227"],"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 local attacker can trigger kernel warnings and potential instability by changing RX ring parameters on Intel I225/I226 network interfaces.","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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nigc: avoid kernel warning when changing RX ring parameters\n\nCalling ethtool changing the RX ring parameters like this:\n\n  $ ethtool -G eth0 rx 1024\n\non igc triggers kernel warnings like this:\n\n[  225.198467] ------------[ cut here ]------------\n[  225.198473] Missing unregister, handled but fix driver\n[  225.198485] WARNING: CPU: 7 PID: 959 at net/core/xdp.c:168\nxdp_rxq_info_reg+0x79/0xd0\n[...]\n[  225.198601] Call Trace:\n[  225.198604]  \u003cTASK\u003e\n[  225.198609]  igc_setup_rx_resources+0x3f/0xe0 [igc]\n[  225.198617]  igc_ethtool_set_ringparam+0x30e/0x450 [igc]\n[  225.198626]  ethnl_set_rings+0x18a/0x250\n[  225.198631]  genl_family_rcv_msg_doit+0xca/0x110\n[  225.198637]  genl_rcv_msg+0xce/0x1c0\n[  225.198640]  ?
