This\nindicates that urb->context, which contains struct si470x_device\nobject, is freed when si470x_int_in_callback() is called.\n\nThe cause of this issue is that si470x_int_in_callback() is called for\nfreed urb.\n\nsi470x_usb_driver_probe() calls si470x_start_usb(), which then calls\nusb_submit_urb() and si470x_start().  If si470x_start_usb() fails,\nsi470x_usb_driver_probe() doesn't kill urb, but it just frees struct\nsi470x_device object, as depicted below:\n\nsi470x_usb_driver_probe()\n  ...\n  si470x_start_usb()\n    ...\n    usb_submit_urb()\n    retval = si470x_start()\n    return retval\n  if (retval < 0)\n    free struct si470x_device object, but don't kill urb\n\nThis patch fixes this issue by killing urb when si470x_start_usb()\nfails and urb is submitted.  If si470x_start_usb() fails and urb is\nnot submitted, i.e. submitting usb fails, it just frees struct\nsi470x_device object."}],"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-416"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.6","versionEndExcluding":"4.9.337","matchCriteriaId":"9DB1B0E4-EEEF-4E3F-874D-0DF40E79F079"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"4.14.303","matchCriteriaId":"1E7450AD-4739-46F0-B81B-C02E7B35A97B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.15","versionEndExcluding":"4.19.270","matchCriteriaId":"AE8904A3-99BE-4E49-9682-1F90A6373F4F"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.4.229","matchCriteriaId":"A0C0D95E-414A-445E-941B-3EF6A4D3A093"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.163","matchCriteriaId":"D05D31FC-BD74-4F9E-B1D8-9CED62BE6F65"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.86","matchCriteriaId":"47237296-55D1-4ED4-8075-D00FC85A61EE"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.0.16","matchCriteriaId":"C720A569-3D93-4D77-95F6-E2B3A3267D9F"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.1.2","matchCriteriaId":"77239F4B-6BB2-4B9E-A654-36A52396116C"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0ca298d548461d29615f9a2b1309e8dcf4a352c6","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/146bd005ebb01ae190c22af050cb98623958c373","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/1c6447d0fc68650e51586dde79b5090d9d77f13a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/52f54fe78cca24850a30865037250f63eb3d5bf7","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/63648a7bd1a7599bcc2040a6d1792363ae4c2e1b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/6c8aee0c8fcc6dda94315f7908e8fa9bc75abe75","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/7d21e0b1b41b21d628bf2afce777727bd4479aa5","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/8c6151b8e8dd2d98ad2cd725d26d1e103d989891","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/92b0888398e4ba51d93b618a6506781f4e3879c9","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
