This is due to the fact that there\nisn't a q_vector associated with the test ring when it is setup as\ninterrupts are not normally added to the test rings.\n\nTo address this I have added code that will check for a q_vector before\nreturning a napi_id value. If a q_vector is not present it will return a\nvalue of 0."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ixgbe/ixgbe_main.c"],"versions":[{"version":"b02e5a0ebb172c8276cea3151942aac681f7a4a6","lessThan":"758d19098df4b0bbca9f40d6ae6c82c9c18b9bba","status":"affected","versionType":"git"},{"version":"b02e5a0ebb172c8276cea3151942aac681f7a4a6","lessThan":"31166efb1cee348eb6314e9c0095d84cbeb66b9d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ixgbe/ixgbe_main.c"],"versions":[{"version":"5.11","status":"affected"},{"version":"0","lessThan":"5.11","status":"unaffected","versionType":"semver"},{"version":"5.11.16","lessThanOrEqual":"5.11.*","status":"unaffected","versionType":"semver"},{"version":"5.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.11.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/758d19098df4b0bbca9f40d6ae6c82c9c18b9bba"},{"url":"https://git.kernel.org/stable/c/31166efb1cee348eb6314e9c0095d84cbeb66b9d"}],"title":"ixgbe: Fix NULL pointer dereference in ethtool loopback test","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-04T05:17:42.887Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/758d19098df4b0bbca9f40d6ae6c82c9c18b9bba","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/31166efb1cee348eb6314e9c0095d84cbeb66b9d","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2021-46916","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:02:07.223543Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:33:31.253Z"}}]}}
