It will ensure the attribute being described produces\na valid nlattr pointer in info->attrs before entering into each handler\nin vdpa_nl_ops.\n\nThat is to say, the missing part in vdpa_nl_policy may lead to illegal\nnlattr after parsing, which could lead to OOB read just like CVE-2023-3773.\n\nThis patch adds the missing nla_policy for vdpa max vqp attr to avoid\nsuch bugs."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.198","versionEndExcluding":"6.1.47","matchCriteriaId":"638778C1-5F03-4F56-AE33-745E57C94BA6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.4.12","matchCriteriaId":"CF8ECF64-40AE-49AB-8315-4D83F9F56ECF"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc1:*:*:*:*:*:*","matchCriteriaId":"0B3E6E4D-E24E-4630-B00C-8C9901C597B0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc2:*:*:*:*:*:*","matchCriteriaId":"E4A01A71-0F09-4DB2-A02F-7EFFBE27C98D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc3:*:*:*:*:*:*","matchCriteriaId":"F5608371-157A-4318-8A2E-4104C3467EA1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc4:*:*:*:*:*:*","matchCriteriaId":"2226A776-DF8C-49E0-A030-0A7853BB018A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc5:*:*:*:*:*:*","matchCriteriaId":"6F15C659-DF06-455A-9765-0E6DE920F29A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.5:rc6:*:*:*:*:*:*","matchCriteriaId":"5B1C14ED-ABC4-41D3-8D9C-D38C6A65B4DE"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5d6ba607d6cb5c58a4ddf33381e18c83dbb4098f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ea65e8b5e6b1a34deda7564f09c90e9e80db436a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ff71709445ac033e6e250d971683110e4781c068","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
