On basis of this fact\nsimplify the code by removing operations with pwm->hwpwm, there is no\ncontrols which require channel number as input.\n\nEven though I wasn't aware at the time when I forward ported that patch,\nthis fixes a null pointer dereference as lpc32xx->chip.pwms is NULL\nbefore devm_pwmchip_add() is called."}],"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:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9.284","versionEndExcluding":"4.10","matchCriteriaId":"6D5E2E93-CF7C-4EB8-A897-64BAD08711B7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.14.248","versionEndExcluding":"4.14.326","matchCriteriaId":"416B8F88-942F-4850-9092-1038ECDD429B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19.208","versionEndExcluding":"4.19.295","matchCriteriaId":"B23BA97E-A1DF-414D-8E03-D3657F31B448"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.149","versionEndExcluding":"5.4.257","matchCriteriaId":"A6D8239E-B285-44F7-84FE-07F052938EE9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10.69","versionEndExcluding":"5.10.195","matchCriteriaId":"39657E45-4B2D-49C0-84C9-71C3DF7DB55C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14.8","versionEndExcluding":"5.15.132","matchCriteriaId":"BE044518-5B3F-43AB-A0D0-D340B46C2255"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.54","matchCriteriaId":"7353B9B4-AFFC-45DE-840E-1A7D2B00E7AD"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.5.4","matchCriteriaId":"CA8C8B88-AF36-445D-A228-AD78F3615373"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/04301da4d87067a989f70ee56942bf9d97cd2a45","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/4aae44f65827f0213a7361cf9c32cfe06114473f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/523f6268e86552a048975749251184c4e9a4b38f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/5e22217c11424ef958ba28d03ff7167b4d7a8914","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a2d9d884e84bfd37892219b1f55847f36d8e9901","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a9a505f5b39d8fff1a55963a5e524c84639e98b2","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/abd9b2ee4047ccd980decbf26d61f9637604b1d5","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e3a0ddbaf7f1f9ffc070718b417461ced3268758","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
