As a result, subsequent attempts to set that device online fail\nwith return code ENODEV.\n\nThe problem occurs when a path verification request arrives after\na wait for final device state completed, but before the result state\nis evaluated.\n\nFix this by ensuring that the CCW-device lock is held between\ndetermining final state and checking result state.\n\nNote that since:\n\ncommit 2297791c92d0 (\"s390/cio: dont unregister subchannel from child-drivers\")\n\npath verification requests are much more likely to occur during boot,\nresulting in an increased chance of this race

occurring."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/s390/cio/device.c"],"versions":[{"version":"2297791c92d04a154ad29ba5a073f9f627982110","lessThan":"3076b3c38a704e10df5e143c213653309d532538","status":"affected","versionType":"git"},{"version":"2297791c92d04a154ad29ba5a073f9f627982110","lessThan":"559f3a6333397ab6cd4a696edd65a70b6be62c6e","status":"affected","versionType":"git"},{"version":"2297791c92d04a154ad29ba5a073f9f627982110","lessThan":"2df56f4ea769ff81e51bbb05699989603bde9c49","status":"affected","versionType":"git"},{"version":"2297791c92d04a154ad29ba5a073f9f627982110","lessThan":"a4234decd0fe429832ca81c4637be7248b88b49e","status":"affected","versionType":"git"},{"version":"2297791c92d04a154ad29ba5a073f9f627982110","lessThan":"2d8527f2f911fab84aec04df4788c0c23af3df48","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/s390/cio/device.c"],"versions":[{"version":"5.15","status":"affected"},{"version":"0","lessThan":"5.15","status":"unaffected","versionType":"semver"},{"version":"5.15.157","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.88","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.29","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.8.8","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"5.15","versionEndExcluding":"5.15.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.1.88"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.6.29"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.8.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3076b3c38a704e10df5e143c213653309d532538"},{"url":"https://git.kernel.org/stable/c/559f3a6333397ab6cd4a696edd65a70b6be62c6e"},{"url":"https://git.kernel.org/stable/c/2df56f4ea769ff81e51bbb05699989603bde9c49"},{"url":"https://git.kernel.org/stable/c/a4234decd0fe429832ca81c4637be7248b88b49e"},{"url":"https://git.kernel.org/stable/c/2d8527f2f911fab84aec04df4788c0c23af3df48"}],"title":"s390/cio:
