If the other thread (for example, from busy_poll) sets\nit to a value >= budget, this thread will continue to run when it should\nstop, and cause memory corruption and panic.\n\nTo fix this issue, save the per-CQ work_done variable in a local variable\nbefore napi_complete_done(), so it won't be corrupted by a possible\nconcurrent thread after napi_complete_done().\n\nAlso, add a flag bit to advertise to the NIC firmware: the NAPI work_done\nvariable race is fixed, so the driver is able to reliably support features\nlike busy_poll."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2022-48985", "ASSIGNER": "cve@kernel.org"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 4.7, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 1.0}}, "publishedDate": "2024-10-21T20:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc5:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc3:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc4:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc6:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc7:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.1:rc8:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.0.13", "versionStartIncluding": "5.16"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.15.83", "versionStartIncluding": "5.15"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2024-11-07T19:35Z"}
