The\ninteger overflow can lead to a heap buffer overflow as num_elems determines\nthe size of the trailing array in elems, and this array is thereafter\nwritten to for each element in attrs.\n\nNote that this vulnerability only affects devices with the\nwiphy->mbssid_max_interfaces member set for the wireless physical device\nstruct in the device driver, and can only be triggered by a process with\nCAP_NET_ADMIN capabilities.\n\nFix this by checking for a maximum of 255 elements in attrs."}],"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-190"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.46","matchCriteriaId":"D8B8CC90-9492-465C-81D4-10DA3B712286"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.4.11","matchCriteriaId":"C36FD9E6-B6D7-4887-8F08-C1F64E139D5C"},{"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"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6311071a056272e1e761de8d0305e87cc566f734","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/7d09f9f255a5f78578deba5454923072bb53b16c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e642eb67b8c10dcce758d549cc81564116e0fa49","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
