On 64-bit systems,\na value > UINT_MAX is silently truncated when stored.\n\nFix the mismatch by using kstrtouint() instead. This rejects values larger\nthan UINT_MAX at parse time, making truncation impossible. Also add a check\nfor value < 1 to reject the 0-delay case, which would cause the poll work to\nspin without delay and consume 100% CPU."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/edac/edac_device_sysfs.c"],"versions":[{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"a60794ee3f453516ab3ed212ba0295ecf890bc8c","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"f856511058c8cb470d6c6c7ce908870adcdc7dc6","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"656e2fe98ac452db4e5b8147d1f33b8c35b4ec4b","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"541fc6f733b32463cf23277637bb07e2aaa00b53","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"ea01c061d839b520f385f112908de1c6e3391327","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"528052af901d6e6bbfa0e52362a70a58a5dd1e43","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"0e022ee4f8e0dc843ba4c80bb75408a7704279af","status":"affected","versionType":"git"},{"version":"e27e3dac651771fe3250f6305dee277bce29fc5d","lessThan":"66cc9dec919dd63d8e4b3d386f7aed3ae684e645","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/edac/edac_device_sysfs.c"],"versions":[{"version":"2.6.23","status":"affected"},{"version":"0","lessThan":"2.6.23","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.23","versionEndExcluding":"7.3-rc2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a60794ee3f453516ab3ed212ba0295ecf890bc8c"},{"url":"https://git.kernel.org/stable/c/f856511058c8cb470d6c6c7ce908870adcdc7dc6"},{"url":"https://git.kernel.org/stable/c/656e2fe98ac452db4e5b8147d1f33b8c35b4ec4b"},{"url":"https://git.kernel.org/stable/c/541fc6f733b32463cf23277637bb07e2aaa00b53"},{"url":"https://git.kernel.org/stable/c/ea01c061d839b520f385f112908de1c6e3391327"},{"url":"https://git.kernel.org/stable/c/528052af901d6e6bbfa0e52362a70a58a5dd1e43"},{"url":"https://git.kernel.org/stable/c/0e022ee4f8e0dc843ba4c80bb75408a7704279af"},{"url":"https://git.kernel.org/stable/c/66cc9dec919dd63d8e4b3d386f7aed3ae684e645"}],"title":"EDAC/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation","x_generator":{"engine":"bippy-1.2.0"}}}}
