Removal can set that bit immediately afterwards and free\ndd->port in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/block/mtip32xx/mtip32xx.c","drivers/block/mtip32xx/mtip32xx.h"],"versions":[{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"521afbd936ac256b7531470b0b9aa96abf9cd853","status":"affected","versionType":"git"},{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"8283049aa5fcb4e84b2b2928b2888903bb8ee12e","status":"affected","versionType":"git"},{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"8a7799597bd683b6bc251fe2edfa9fd1db568a3a","status":"affected","versionType":"git"},{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"4609e0e0be709e974bec9b52c5022136d25e97d3","status":"affected","versionType":"git"},{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"b389dc35a55713ac24a145741e76196fea1663bc","status":"affected","versionType":"git"},{"version":"88523a61558a040546bf7d8b079ae0755d8e7005","lessThan":"68940f841d013192086a0f6d7cfbac2cd079e228","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/block/mtip32xx/mtip32xx.c","drivers/block/mtip32xx/mtip32xx.h"],"versions":[{"version":"3.3","status":"affected"},{"version":"0","lessThan":"3.3","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"3.3","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/521afbd936ac256b7531470b0b9aa96abf9cd853"},{"url":"https://git.kernel.org/stable/c/8283049aa5fcb4e84b2b2928b2888903bb8ee12e"},{"url":"https://git.kernel.org/stable/c/8a7799597bd683b6bc251fe2edfa9fd1db568a3a"},{"url":"https://git.kernel.org/stable/c/4609e0e0be709e974bec9b52c5022136d25e97d3"},{"url":"https://git.kernel.org/stable/c/b389dc35a55713ac24a145741e76196fea1663bc"},{"url":"https://git.kernel.org/stable/c/68940f841d013192086a0f6d7cfbac2cd079e228"}],"title":"block: mtip32xx: synchronize ioctls with device removal","x_generator":{"engine":"bippy-1.2.0"}}}}
